OPSAPS-58019: “SERVICE_PRINCIPAL is required for kinit” error while activating a new environment
If the /etc/krb5.conf file on the Cloudera Manager host contains "include" or "includedir" directives, then you may encounter Kerberos-related failures on both Embedded Container Service and Red Hat OpenShift platforms. You may see the following error in the Database Catalog's metastore pod logs: SERVICE_PRINCIPAL is required for kinit.
To resolve this issue:
  1. SSH into the Cloudera Manager host as an administrator.
  2. Open the /etc/krb5.conf file for editing.
  3. Comment the lines containing include and includedir directives.
  4. Save the changes and exit.
  5. Recreate the environment.
DWX-10403: Executor pods get stuck in pending state with a warning
In rare circumstances, when Impala or Hive executors start up either due to autoscaling or by manually restarting the executors, the pods may get stuck in a pending state with a warning such as "volume node affinity conflict". This happens due to a race condition in the storage class that provides local volumes.
Restart the pods so that they can be rescheduled on new nodes with enough resources.
