Description

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.

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.

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.
