---------------------------------
Summary: Fail to add a component on the same machine with
ambari-server of a new service with no kerberos identity when kerberos enabled
Key: AMBARI-25797
URL: https://issues.apache.org/jira/browse/AMBARI-25797
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.7.6
Reporter: YUBI LEE
When kerberos enabled and an user tries to add a component of a new service
with no kerberos identity in the same machine with ambari-server, it fails
because there is no temporary data directory.
{code:java}
22-12-03 08:09:24,572 ERROR [process-identity-task-9055-thread-0]
CreateKeytabFilesServerAction:175 - The data directory has not been set.
Generated keytab files can not be stored.{code}
I guess it is a side effect of AMBARI-22138.
AMBARI-22138 adds ambari-server's kerberos identity even though the service's
"Service Component Hosts"(`schToProcess`) is empty.
I'll make a PR.
It fixes this problem by just creating tempory directory.
It will be deleted when whole stage finishes.
