Dear CDH, Cloudera Manager, and Cloudera Navigator users,
We are pleased to announce the release of Cloudera Enterprise 5.11.2 (CDH 5.11.2, Cloudera Manager 5.11.2, and Cloudera Navigator 2.10.2).
This release fixes key bugs and includes the following:
- CDH fixes for the following issues:
- HIVE-11418 - Dropping a database in an encryption zone with CASCADE and trash enabled fails
- HIVE-11878 - ClassNotFoundException can possibly occur if multiple jars are registered one at a time in Hive
- HIVE-12762 - Common join on parquet tables returns incorrect result when hive.optimize.index.filter set to true
- HIVE-16660 - Not able to add partition for views in hive when sentry is enabled
- HIVE-16869 - Hive returns wrong result when predicates on non-existing columns are pushed down to Parquet reader
- IMPALA-5355 - Sentry Privileges and roles updated in the wrong order on impala restart
- IMPALA-5197 - Parquet scan may incorrectly report "Corrupt Parquet file" in the logs
- IMPALA-4293 - Query profile should include error log
- IMPALA-5355 - Sentry Privileges and roles updated in the wrong order on impala restart
- IMPALA-5208 - Forked breakpad process blocks indefinitely for WaitForContinueSignal and fails new Impalad process at startup
- IMPALA-5318 - Impala does not always generated fully qualified table names in audit events
- IMPALA-5615 - Compute Incremental stats is broken for general partition expressions
For a full list of upstream JIRAs fixed in CDH 5.11.2, see the issues fixed section of the Release Notes.
- Cloudera Manager fixes for the following issues:
- Make Oozie Load-balancer URL mandatory when enabling Oozie HA: Fixed an issue when the Oozie Load Balancer field in the Oozie configuration is not set and Oozie high availability is in use (two or more Oozie Server roles are deployed). This now creates a validation error and Cloudera Manager does not let you start or restart Oozie until the problem is fixed.
- Peak Memory Usage report for Impala is broken on CDH 5.11: Fixed an issue where the Impala Peak Memory Usage page in the Cluster Utilization Report did not display any data in Cloudera Manager versions 5.9 to 5.11.
- Agent process directories re-mounted on agent restart: Fixed an issue where restarting an agent on newer Linux distributions such as Ubuntu 16.04 or Red Hat 7 would result in process run directories being remounted and lost.
- Hostname parameter is not passed to Impala catalog role: IMPALA-5253 contained a security fix for clusters using Impala with TLS (SSL) security enabled. This fix was also made in several maintenance versions of CDH that require you to upgrade Cloudera Manager. If you upgrade to a CDH version with this fix without upgrading Cloudera Manager, Impala will not function when TLS is enabled for Impala. You should upgrade Cloudera Manager first if you want to move to a CDH version with the security fix.
CDH versions with the Impala security fix:
To workaround this issue, upgrade to one of the following versions of Cloudera Manager before upgrading CDH:
- 5.12.0
- 5.11.2
- 5.10.2
- 5.9.3
- 5.8.6
