DataStax Enterprise 4.7 release notes 

DataStax Enterprise release notes cover cluster requirements, upgrade guidance, components, changes and enhancements, issues, and resolved issues for DataStax Enterprise 4.7 releases.

DataStax Enterprise release notes cover cluster requirements, upgrade guidance, components, changes and enhancements, issues, and resolved issues for DataStax Enterprise 4.7 releases:

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 DSE Standard, or all 5 Nodes must be DSE Max. 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 

The latest version of DataStax Enterprise 4.7 is 4.7.9.

4.7 Resolved issues

Resolved issues from DataStax Enterprise 4.6.7 and earlier are included.

  • JMX defaults to binding only localhost to mitigate "CVE-2015-0225: Apache Cassandra remote execution of arbitrary code."

    After you upgrade to DataStax Enterprise 4.7, get the latest default values from cassandra-env.sh and ensure that your local cassandra-env.sh file has the latest default values. If you require remote access of JMX, you can safely enable remote JMX access by turning on JMX security. The latest default values from cassandra-env.sh are:

    LOCAL_JMX=yes
    if [ "$LOCAL_JMX" = "yes" ]; then  
        JVM_OPTS="$JVM_OPTS -Dcassandra.jmx.local.port=$JMX_PORT -XX:+DisableExplicitGC"
    else  
        JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.port=$JMX_PORT"  
        JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.rmi.port=$JMX_PORT"  
        JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.ssl=false"  
        JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.authenticate=true"  
        JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.password.file=/etc/dse/cassandra/jmxremote.password"
    fi
    JVM_OPTS="$JVM_OPTS$JVM_EXTRA_OPTS"
  • Analytics jobs use the broadcast address to connect to nodes even when ec2snitch or another snitch that supports public vs private is used. (DSP-3694)
  • Improve error handling in case of core creation failures. (DSP-4110)
  • Speed up dsetool. (DSP-4396)
  • Integrate Spark SQL command line. (DSP-4399)
  • Transitional authenticators do not work with the native protocol. (DSP-4620)
  • Upgrade PySpark support to Spark 1.2 (DSP-4660)
  • The Cassandra context is removed. Use the Spark context instead. (DSP-4672)
  • Delete by query failing on mixed workload clusters. (DSP-4675)
  • LDAP authenticator allows empty password to be authenticated. (DSP-4687)
  • Race condition while loading secondary indexes upon upgrade. (DSP-4689)
  • CompoundFileDirectory exceptions. (DSP-4848)
  • DseDaemon throw NPE in safeStop if failure occurs in startup. (DSP-4865)
  • Fix Solr document expiration when row has already been physically deleted from Cassandra. (DSP-4869)
  • NPE when using Solr data import handler. (DSP-4888)
  • Upgrade to Java driver 2.1.5. (DSP-4947)
  • Plugin/stats not showing in the Solr Admin UI. (DSP-5007)
  • Installed JNA is no longer used. (DSP-5033)
  • Creating solr_query column before using dsetool causes solr queries in CQL to fail. (DSP-5105)
  • Can't run describe keyspace in cqlsh on Solr core. (DSP-5117)
  • Block incremental repair operations on remote anti-compaction. (DSP-5331)
  • Removed CQLStorage handler, migrate the tables to CqlNativeStorage format that uses Cql Record Reader. (DSP-5538)
4.7 Issues
  • Dynamic fields of the Solr type LatLongTypeSolr are not supported. (DSP-5002)
  • Creating indexes with DEFERRED REBUILD is not supported in Spark SQL; a new column defaults to empty instead of none. (DSP-4713)
  • Solr_query fails in mixed upgrade state because of Solr pagination. (DSP-5334)

    On a cluster with mixed versions of DSE, for example 4.6 and 4.7, where only the 4.7 version supports pagination, issuing queries from the 4.7 nodes returns only FetchSize results because 'FetchSize' is the driver iused when executing the query. To workaround this limitation, disable driver pagination so that Solr pagination is also disabled for the queries on 4.7 nodes.

  • When starting DSE in Hadoop mode, an exception might occur that is related to the Task Tracker initially being unable to connect to the JobTracker. Automatic and immediate retry successfully connects and and does not impact Hadoop performance. (DSP-5621)
