Azul Open JDK 8 and 11 are not supported with Cloudera Manager. To use Azul Open JDK 8 or 11 for Cloudera Manager RPM/DEBs, you must manually create a symlink between the Zulu JDK installation path and the default JDK path.

After installing Azul Open JDK8 or 11, you must run the following commands on all the hosts in the cluster:
Azul Open JDK 8
RHEL or SLES
# sudo ln -s /usr/lib/jvm/java-8-zulu-openjdk-jdk /usr/lib/jvm/java-8-openjdk
Ubuntu or Debian
# sudo ln -s /usr/lib/jvm/zulu-8-amd64 /usr/lib/jvm/java-8-openjdk
Azul Open JDK 11
For DEBs only
# sudo ln -s /usr/lib/jvm/zulu-11-amd64 /usr/lib/jvm/java-11
Following are the list of fixed issues that were shipped for Cloudera Manager 7.6.7 CHF2 (version: 7.6.7-h2-38250798):
  • OPSAPS-65104
    Importing table column statistics for Hive replication is thread-safe but causes performance regression.
    To resolve this issue, perform the following steps:
    1. Go to the Cloudera Manager > Clusters > Hive service > Configuration tab.
    2. Locate the hive_replication_env_safety_valve property.
    3. Add only one of the following key-value pair depending on your requirement:
      • COLUMN_STATS_IMPORT_MULTI_THREADED=true

        This ensures that the column statistics import operation is multi-threaded for Hive replication.

      • SKIP_COLUMN_STATS_IMPORT=true

        This ensures that the column statistics import is skipped entirely.
