{code}
*Cause*
In the following code snip, {{targetStackID}} is {null}}:
{code:title=org/apache/ambari/server/serveraction/upgrades/UpgradeUserKerberosDescriptor.java:103}
StackId targetStackId =
getStackIdFromCommandParams(KeyNames.TARGET_STACK);
{code}
This causes the logic in {{UpgradeUserKerberosDescriptor}} to be skipped.
*Solution*
Change the code snip from above to
{code:title=org/apache/ambari/server/serveraction/upgrades/UpgradeUserKerberosDescriptor.java:103}
StackId targetStackId = cluster.getDesiredStackVersion();
{code}
