, the data is immediately
expired and purged on the next compaction. When using a long TTL, DataStax strongly recommends
upgrading to DataStax Enterprise 4.8.16 and taking required action. 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.
Before you upgrade
- Be sure to read the DataStax Enterprise Upgrade Guide.
- Be sure to check driver compatibility.

- Delete (unload_core) a Solr index without deleting/dropping the underlying keyspace and table. (DSP-1533)
- DSE Search supports indexing and querying of Cassandra tuples and user defined types (UDTs). (DSP-3748)
- Support SELECT count() in CQL Solr queries. (DSP-4843)
- Solr Data Import Handler is deprecated. Use parquet or JSON instead. For Spark earlier than 1.4, use the DataReader API. (DSP-4887)
- Support dynamic field Solr LatLonType with spatial subfield prefix naming conventions. (DSP-5021)
- Enable slow query log collection by default, change dse.yaml options and default values. (DSP-5211)
- DSE Search supports advanced spatial queries for polygon shapes. Use installation script for JTS. (DSP-5320)
- Audit filter in dse.yaml can filter on keyspaces using a regular expression. (DSP-5407)
- Restrict HTTP and Solr Admin access to DSE Search. Create a Tomcat connector or use rpc_address in cassandra.yaml. (DSP-5440)
- Audit log tables use DateTieredCompactionStrategy (DTCS). (DSP-5462)DataStax recommends changing tables that were created in earlier releases to use DTCS:
ALTER TABLE dse_audit.audit_log WITH COMPACTION={'class':'DateTieredCompactionStrategy'};
- Implement updateDocuments for block join in live indexing. (DSP-5506)
- Node health change and new commands to inspect node health and indexing status.
(DSP-5508)
- Node health options are always enabled. You can customize the refresh rate for node_health_options in dse.yaml.
- Use the dsetool node_health command to retrieve a dynamic score between 0 and 1 that describes the health of a DataStax Enterprise node.
- Use the dsetool core_indexing_status command to retrieve the dynamic indexing status (INDEXING, FINISHED, or FAILED) of the specified core in a DSE Search node.
- The CassandraStorage() handler is deprecated. Use CqlNativeStorage() instead. Thrift-based Hadoop classes that are not Java-driver based are deprecated. (DSP-5750)
- Support for Shark is removed. Use Spark SQL instead. (DSP-5824)
- Automatically insert CQLSearchHandler into solrconfig.xml. (DSP-5831)
- Integrate Spark Jobserver. (DSP-5827)
- The configuration of credentials for the Spark SQL Thrift Server is controlled by the hive-site.xml file in the Spark directory. (DSP-5927)
- DseSparkConfHelper, DseSparkContext, DseStreamingContext are deprecated. DataStax Enterprise configuration is applied with scripts at startup. Using Spark requires no modifications. (DSP-5987)
- Reduce search index size by providing a way to disable DSE from adding _partitionKey field to Solr documents. (DSP-6021)
- The dse client-tool supports basic operations that
are required to run client applications. (DSP-6025)
- In the authenticated cluster, provide Cassandra credentials instead of JMX username and password.
- The
dsetool sparkmaster
command is deprecated, and is replaced by the dse client-tool spark master-address command. - Replaces the
dsetool jobtracker
command.
- The multi-threaded indexing back pressure algorithm provides improved performance, reliability, and visibility. (DSP-6103)
- DSE PySpark Scala wrappers are deprecated. PySpark and DSE PySpark are still supported using the more efficient DataFrames API. (DSP-6203).
- BYOH Hive is deprecated and will be removed in a future release. (DSP-6337)
- Integrate Spark 1.4. (DSP-6356)
- You can use an ODBC or JDBC client to interact with the Spark SQL Thrift server. When reading and writing large amounts of data, DataStax recommends using the Cassandra-backed DataFrames. (DSP-6385)
- Parameter name change for the Spark Connector property: spark.cassandra.input.page.row.size is renamed to spark.cassandra.input.fetch.size_in_rows.
- G1GC Java Garbage Collector is enabled by default when DataStax Enterprise runs under Java 8. (DSP-6392)
- In DSE Search, Solr deep paging is off by default and is configurable. (DSP-6400)Set the cql_solr_query_paging option in the dse.yaml file as appropriate for the workload.
- For development clusters in mixed workloads, DataStax recommends using the default cql_solr_query_paging: off setting to turn paging off. This cql_solr_query_paging: off setting is helpful for a mixed workload cluster where normal search queries are run.
- For SearchAnalytics nodes, DataStax recommends using the cql_solr_query_paging: driver setting. This cql_solr_query_paging: driver setting is helpful when analytics nodes leverage search.
- Verify all unique key elements are indexed in Solr schema. (DSP-6460)
- HiveServer2 authentication changes in a secured cluster. (DSP-6508)
- Deleted doc might show in a DSE Search query when using facet tagging and excluding filters or query result cache is on. (DSP-6529)
- Improve indexing performance by using multi-thread indexing for wide rows. (DSP-6592)
- The default log directory is changed to $HOME/spark-thrift-server for starting the spark-thrift-server. (DSP-6720)
- CqlBulkOutputFormat is broken by upgrade to Cassandra 2.1. (DSP-4875)
- Spark executors use cassandra.yaml and dse.yaml to get information about SSL and Kerberos. (DSP-5576)
- Bootstrapping TDE nodes try to read from themselves. (DSP-5701)
- The dse startup script hard codes ulimits for the cassandra user. (DSP-5713)
- Permissions set by the DSE/Cassandra installation process on the /var/lib/cassandra directory are 750 by default. Permissions are now 751. (DSP-5970)
- Remove query docFreq lookup for filters. (DSP-5982)
- WAIT_FOR_START=10 is too low on an m1.large instance type. (DSP-6077)
- Hive connector uses yaml files and property names that are not DSE-compatible. (DSP-6042)
- DSE Spark --jars flag does not work. (DSP-6087)
- The value of load_max_time_per_core is too low by default. (DSP-6260)
- Range tombstones might cause unwanted deletes from the index. (DSP-6301)
- NullPointerException thrown in Solr when enabling live indexing. (DSP-6336)
- Remove unnecessary contention and improve live indexing reader latency by removing usage of RAMFile for deletes. (DSP-6362)
- Failure to close key iterator could lead to reference leaks. (DSP-6377)
- Cannot set max_solr_concurrency_per_core at 1. (DSP-6408)
- Single pass queries do not work with UUID, TimeUUID, Inet, Decimal, and Varint types. (DSP-6443)
- "_docBoost" prevents docs from being indexed. (DSP-6486)
- enable_back_pressure_adaptive_nrt_commit is not set to true by default. (DSP-6453)
- Changes in spark-env.sh do not get picked up properly after restart. (DSP-6502)
- Portfolio manager web interface broken. (DSP-6593)
- Solr re-index progress does not show in OpsCenter Activity. (DSP-6613)
- Allow for configuring the NIO connector via Tomcat server.xml. (DSP-6645)The BIO connector is more performant. However, you can revert back to NIO by setting the protocol to
org.apache.coyote.http11.Http11NioProtocol
in the Tomcat server.xml file under ~/dse/resources/tomcat/conf:
After you start DataStax Enterprise, you can verify the NIO connector with these lines in the Tomcat Catalina log file:<Connector port="${http.port}" protocol="org.apache.coyote.http11.Http11NioProtocol" connectionTimeout="20000" redirectPort="8443" URIEncoding="UTF-8"/>
Sep 14, 2015 11:22:39 PM org.apache.coyote.http11.Http11NioProtocol init INFO: Initializing Coyote HTTP/1.1 on http-8983 Sep 14, 2015 11:22:41 PM org.apache.coyote.http11.Http11NioProtocol start INFO: Starting Coyote HTTP/1.1 on http-8983
- Top deletion might cause unwanted deletes from the index. (DSP-6654)
- 2GB SSTable limitation for In-Memory table per node. (DSP-6685)
- DSE Search: Setting Solr concurrency by JMX causes deadlock with index flushing.
(DSP-6772)
If you use JMX to set IndexPool Concurrency, a deadlock occurs for index workpool flushing. Indexing stops until the time that is set for flush_max_time_per_core is reached.
Workaround: Do not use JMX to set IndexPool Concurrency. If you need to change IndexPool Concurrency, edit the dse.yaml file to change max_solr_concurrency_per_core and restart the node.
- To improve index performance, set production appropriate mergeScheduler values for DSE Search with near real time (NRT) indexing. See Configuring and tuning indexing performance. (DSP-9325)
