Fixed issues in 1.5.4 SP2

This section lists issues fixed in this release for Cloudera AI on premises.

DSE-40909: Disabled 'Run experiments' function does not work as expected

When the Administrator disabled 'running experiments' in Cloudera AI Workbench > Site Administration > Settings, the user was still able to see the Experiments menu item in the global- and project-level navigation.

With the help of implementing the sufficient conditions the UI can now hide the disabled function.

DSE-38645: spark.yarn.jars are not set properly in Cloudera AI on premises Spark Pushdown mode

In case of Spark pushdown, the spark.yarn.jars parameter can indicate which jars in the driver shall be transported to YARN executors. Without this parameter set, the YARN executors use the Spark jars from the base cluster provided by Cloudera Distribution of Spark. This can lead to version mismatch between the Spark driver (used Cloudera Data Engineering-provided jars) and the executors.

Now, the spark.yarn.jars parameter is set to use jars from the Cloudera AI driver (Cloudera AI session) to keep the versions matched between the Spark driver and the executors.

DSE-39798: API v1 stop session endpoint shall perform authentication check
Previously, users could stop sessions under projects that they were not authorized to access using the session’s Universally unique identifier (UUID). This issue is now resolved.
DSE-41431: Register engine stopped status

When the reconciler is overloaded with a large number of events, the deleted status is still propagated to ensure that engines do not remain in 'Stopping' status.

DSE-41424: Better handling for data connection validation errors

In Cloudera AI on premises 1.5.4 SP1 Cloudera AI Workbench failed to start under the following conditions:

  • If the HIVE_ON_TEZ service was not present or the following configurations were missing:

    • hiveserver2_load_balancer

    • hive.server2.transport.mode

    • Kerberos_princ_name

  • If the IMPALA service was not present on your Base cluster or the following configurations were missing:

    • Hs2_port or hs2_http_port

    • Kerberos_princ_name

This issue has been fixed.

DSE-41218: Restrict secrets and ingress access from User Service Account role

User access to Kubernetes secrets and ingresses in their own user namespace has been removed.

DSE-34314: Cloudera Base AutoTLS property set incorrectly
The correction to Cloudera Base AutoTLS configurations resulted in the atlas.kafka.ssl.truststore.location value to be set incorrectly.

This issue has been fixed.
