> 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.
