[jira] [Created] (HIVE-17560) HiveMetastore doesn't start in secure cluster if repl change manager is enabled

Thejas M Nair created HIVE-17560:
------------------------------------

             Summary: HiveMetastore doesn't start in secure cluster if repl change manager is enabled
                 Key: HIVE-17560
                 URL: https://issues.apache.org/jira/browse/HIVE-17560
             Project: Hive
          Issue Type: Bug
            Reporter: Thejas M Nair
            Assignee: Thejas M Nair
             Fix For: 3.0.0


When hive.repl.cm.enabled=true, ReplChangeManager tries to access HDFS before metastore does kerberos login using keytab.
Metastore startup code doesn't do an explicit login using keytab, but instead relies on kinit by saslserver for use by thrift to do it.

It would be cleaner to do an explicit UGI.loginFromKeytab instead to avoid such issues in future as well.
