DataStax Enterprise 5.0 release notes

Requirement for Uniform Clusters 

All Nodes in each Cluster must be uniformly licensed to use the same Subscription. For example, if a Cluster contains 5 Nodes, all 5 Nodes within that Cluster must be either DataStax Basic, or all 5 Nodes must be DataStax Enterprise. Mixing different Subscriptions within a Cluster is not permitted. “Cluster” means a collection of Nodes running the Software which communicate with one another via Gossip, and “Gossip” means the mechanism within the Software enabling related Nodes to communicate with one another. For more information, see Enterprise Terms.

5.0.15 Highlights 

DSE Analytics and DSEFS 5.0.15 highlights 

• CRITICAL Fixed a race condition that could corrupt data retrieved from DSEFS or cause spurious FileNotFoundExceptions and other problems under very heavy load. (DSP-17178)
• CRITICAL Security improvement: DSEFS uses an isolated native memory pool for file data and metadata sent between nodes. This isolation makes it harder to exploit potential memory management bugs. (DSP-16492)
• Improved reliability of DSEFS startup when some nodes in the cluster cannot be reached. (DSP-16875)
• Fixed DSEFS startup crash caused by using a duration type in non-dsefs keyspaces. (DSP-16825)

Spark bug fixes:

• DataStax Spark Cassandra Connector: Upgraded Java driver to version 3.0.8. Fixes duplicate UUID generation problem that can happen when running multiple Spark executors on the same node. (DSP-15643)
• Fixed reading from external filesystem (S3, HDFS) based external tables. (DSP-16561)

Improvements:

• DataStax Spark Cassandra Connector: Avoid a freeze on exit of Spark applications (including Spark shell), if the application program does not close the Spark context. (DSP-16051)
• Reduced the number of internode connections kept open by DSEFS. (DSP-14284)
• Improved DSEFS diagnostics and logging. (DSP-16101)

DSE Graph 5.0.15 highlights 

• Changing search index schema using a gremlin script is supported. (DSP-15831)
• Deleting a search index that was defined inside a graph no longer fails. (DSP-16765)

DSEFS 5.0.15 changes and enhancements 

• Improved handling of DSEFS client idle connection. (DSP-14284)
• Security improvement: DSEFS uses an isolated native memory pool for file data and metadata sent between nodes. This isolation makes it harder to exploit potential memory management bugs. (DSP-16492)

• Added convenience methods for reading graph configuration: getEffectiveAllowScan and getEffectiveSchemaMode. (DSP-16650)
• The hardcoded default schema_mode is changed from Development to Production. (DSP-16650)

DSE Search 5.0.15 changes and enhancements 

• If a client executes a query that results in a shard attempting to send an internode frame larger than the size specified in frame_length_in_mb, the client receive an error message with a message like this:

  Attempted to write a frame of <n> bytes with a maximum frame size of <n> bytes
  

  In earlier versions, the query timed out with no message. Information was provided only as error in the logs.

5.0.10 Components 

5.0.10 Highlights 

DSE Enterprise 5.0.10 highlights 

DSE Analytics and DSEFS 5.0.10 highlights 

• DSE Analytics safety feature prevents DSE from starting up if the Spark data directories are not present when DSEFS is enabled and the data directories are missing. This safety check resolves problems in earlier releases where DSE would start, but analytics nodes could experience hard-to-detect problems. (DSP-13238, DSP-13245)
• DSEFS includes important stability fixes and performance improvements. To use DSEFS in production, DataStax strongly recommends upgrading DSE 5.0.9 and earlier installations to DSE 5.0.10 to leverage these improvements.

5.0.10 highlights 

• improved DSE Graph Loader custom id support for multiple keyed vertices. (DGL-258)
• Improved stability by limiting the number of supported vertex labels, disallowing the multi-properties for the partition key, removing provisioning during graph creation, and deprecating PVTs. (DSP-14300, DSP-11078, DSP-13501)
• Upgraded TinkerPop to improve the performance and support DSL in Gremlin. (DSP-13545, DSP-13828, DSP-13467)

DSE Search 5.0.10 highlights 

DataStax Enterprise 5.0.10 Changes and enhancements 

DataStax Enterprise core changes and enhancements 

After upgrades from DSE 5.0.0-5.0.9 to DSE 5.0.10 or later, you must follow instructions in the upgrade guide to migrate off of incremental repairs. To continue running incremental repairs, use nodetool repair -inc.

DSE Analytics 5.0.10 changes and enhancements 

• When ALLOW_SPARK_HOME=true, support to specify a user-specific Spark home directory with the SPARK_HOME environment variable. (DSP-8100)
• Documentation for removing a node running DSEFS. (DSP-13701)
• Improved troubleshooting capabilities by including keyspace name in Hive Connector CL log warning message. (DSP-14184)

DSEFS 5.0.10 changes and enhancements 

• Performance and stability of listing DSEFS directories with thousands of entries is improved. (DSP-13812)
• DSEFS read performance is improved. (DSP-13309)
• Connection reuse is improved. Closing idle connections is disabled by default. New idle_connection_timeout_ms option in dse.yaml defines how long to wait before an idle client-server connection is closed. (DSP-14010)
• For initial DSEFS connections only, the new DSEFS shell option --prefer-contact-points uses defined contact point to force connecting to a remote node, even if local node is available. (DSP-14108)

DSE Graph 5.0.10 changes and enhancements 

• Improved and simplified data batch loading of preformatted data. (DGL-235)

  Supporting changes:

  • Schema discovery and schema generation are deprecated. (DGL-246)
  • Standard IDs are deprecated. (DGL-247)
  • Transformations are deprecated. (DGL-248)
  • Standard vertex IDs are deprecated. Use custom vertex IDs instead. (DSP-13485)
• improved DSE Graph Loader custom id support for multiple keyed vertices. (DGL-258)
• Don't instantiate DseQueryHandler for each statement in graph. (DSP-13287)
• Graph profile() results should display CQL by default even in console. (DSP-13292)
• GraphSON 2.0 serialization performance enhancements. (DSP-13467)
• Partitioned vertex tables (PVTs) are deprecated. (DSP-13501)
• Do partition deletes for the property/edge table entries, if possible. (DSP-13671)
• Remove provisioning state during graph creation. Graph is either live or non-existing. (DSP-13686)
• Improved support for domain-specific languages (DSL) in Gremlin enables the DataStax driver to specify TraversalSource. (DSP-13545)
• cache=false at the transaction level now includes disabling AdjacencyListStoreImpl and IndexStoreImpl. (DSP-13560)
• Timeouts for graph traversals now start from the time the request is received. Earlier releases started timeouts for graph traversals at processing start time. Timeouts will appear more readily on an overloaded server. (DSP-13828)
• Numeric sack values no longer need to be explicitly typed (for example, 3.0D). You can still provide for greater specificity in the expected return type. (DSP-14026)
• Lambdas provided to the sack() step are now recognized by the LambdaRestrictionStrategy. You must disable the restrict_lambda setting to call this method. (DSP-14118)
• Gremlin console uses the default plugins.txt in the DSE distribution. If a user home is specified with bin/dse gremlin-console ~/gremlin-console then extra checks are performed to ensure that plugins.txt is populated. (DSP-14286)
• Prevent multi-properties for the partition/clustering key. (DSP-14300)

DSE Search 5.0.10 changes and enhancements 

• Full validation on all schema fields might result in validation failures after upgrade. (DSP-6501)
  • All field definitions in the schema are validated and must be DSE Search compatible, even if the fields are not indexed, have docValues applied, or used for copy-field source.
  • Tune the schema before you upgrade. All field definitions in the schema are validated and must be DSE Search compatible, even if the fields are not indexed, have docValues applied, or used for copy-field source. With the tuned index, performance gains are especially recognized for unused large blobs.
• rtOffheapPostings is present by default in demo and auto-generated solrconfig.xml files. (DSP-10088)
• The default filter cache settings are changed. (DSP-13153)
• DSE Search indexing optimizes for SSDs by default. Spinning disk detection logic is removed. (DSP-13924)
• Improved error messages on invalid solr_query are more descriptive for invalid queries and syntax errors. (DSP-14003)
• The table system_auth.resource_role_permissons_index is no longer used. Drop this table after all nodes are upgraded to DSE 5.0.10. upgrades from DSE 5.0.10+ to DSE versions earlier than 5.1.3 are not recommended. (DSP-14159)

5.0.10 Resolved issues 

5.0.10 DataStax Enterprise core resolved issues

• Simplify role-permissions handling (DSP-14159)
• Prevent marking remote SSTables shadowing compacted data as repaired. (DSP-14141)
• CPU layout assertions on startup should show in log file instead of stopping startup. (DSP-14281)
• Completed rebuild logging always says 0 bytes. (DSP-13870)
• nodetool rebuild and bootstrap improvements. (DSP-13870)
• Incremental repairs are the default for nodetool repair, even with nodetool repair -full or nodetool repair -pr are incremental. (DSP-14464)

  After upgrades from DSE 5.0.0-5.0.9 to DSE 5.0.10, you must follow instructions in the upgrade guide to migrate off of incremental repairs. To continue running incremental repairs, use nodetool repair -inc.

5.0.9 Components 

5.0.9 Highlights 

5.0.9 DSE Enterprise highlights 

DataStax Enterprise 5.0.9 includes CASSANDRA-13004 that fixes possible corruption while adding a column to a table or removing a column from a table. (DSP-13684)

This fix requires a messaging protocol version change to VERSION_3014. DataStax strongly recommends additional steps for upgrades from 5.0.0 through 5.0.8 to DSE 5.0.9 and later.

5.0.9 DSE Analytics and DSEFS highlights 

• Improved DSEFS performance when authorization is enabled. (DSP-13107).
• The SparkBuildExample project was updated with tags to cover several recent DSE releases.

5.0.9 DSE Search highlights 

5.0.9 Changes and enhancements 

5.0.9 DataStax Enterprise core changes and enhancements 

• New nodetool sjk command for troubleshooting and monitoring that runs Swiss Java Knife (SJK) on the local node. (DSP-13544)
• Skip complex column range tombstones on simple columns. (DSP-13644)
• Fail remaining ongoing tasks when aborting a repair job. (DSP-13544)
• On node failure, fail only repair tasks of that node. (DSP-13544)
• Coerce integer JSON values to timestamp as well as long values. (DSP-13644)
• Integrate top threads command in nodetool. (DSP-13544)

5.0.9 DSE Analytics changes and enhancements 

• DSEFS: Improve error message when DSEFS is low on storage space. (DSP-13324)
• DSEFS: Add local cache for name and inode retrieval to improve authorization performance. (DSP-13107)

5.0.9 DSE Graph changes and enhancements 

• Make explicit parameter for setting tmp dir for mapdb and netty. (DGL-167)
• Support recursive loading of directories. (DGL-172)
• Specify file matching pattern for directory load. (DGL-177)
• Remove double cluster client in ClusterBuilder. Instead, use a single client and configure the CL in a SimpleGraphStatement for creating the graph. (DGL-183)
• Support for geospatial data types. (DGL-225)
• Change in schema definition for geo types. For each geo type, you must declare type as geo bound or cartesian bound. (DGL-243)
• Include additional remote error information for Gremlin processing failures with TinkerPop protocol. (DSP-13112)
• A change is required if more than 256 parameters are passed on a graph query request for TinkerPop drivers and drivers using Cassandra native protocol. Passing very large numbers of parameters on requests is an anti-pattern, because the script evaluation time increases proportionally. DataStax recommends reducing the number of parameters to speed up script compilation times. Consider alternate methods for parameterizing scripts, like passing a single map. If the graph query request requires many arguments, pass a list. If you pass more than 256 parameters, increase the max_query_params option in dse.yaml. (DSP-12789)

5.0.9 DSE Search changes and enhancements

• dsetool logs clear credentials on logs. (DSP-12985)
• Possible corruption while adding a column to a table or removing a column from a table, see CASSANDRA-13004. (DSP-13684)

5.0.9 DSE Analytics resolved issues 

• When DSE node with Spark Master gracefully shuts down at the same time that an application is submitted or stopped, Spark Master fails to save the recovery storage information. (DSP-12795)
• Change lease manager log message to improve Spark Master troubleshooting. (DSP-12846)

• Gremlin scripts taking a long time to compile. See required change if more than 256 parameters are passed on a graph query request. (DSP-12789)
• gremlin-console isn't properly initialized when started in debug mode. (DSP-12900)
• Incomplete error message for invalid gremlin query with addV(). (DSP-13108)
• Exception thrown when attempting to read IDs of vertices retrieved through a full-graph scan. (DSP-13210)
• Graph should start listening to schema updates only after DSE system keyspace is set up. (DSP-13251)
• Cache empty result sets for queries that didn't return elements. (DSP-13342)
• Change ranking of indices so that Search index < Secondary Index < MV index. (DSP-13212)
• If a gremlin recursive drop() times out, database can be left in an inconsistent state. (DSP-13299)
• Gremlin inside() function no longer uses search index. (DSP-13553)
• Remove unnecessary sharedData.refresh() calls when creating/dropping a graph. (DSP-13779)
