[jira] [Created] (KAFKA-3670) ControlledShutdownLeaderSelector should pick the preferred replica as the new leader, if possible

Jun Rao created KAFKA-3670:
------------------------------

             Summary: ControlledShutdownLeaderSelector should pick the preferred replica as the new leader, if possible
                 Key: KAFKA-3670
                 URL: https://issues.apache.org/jira/browse/KAFKA-3670
             Project: Kafka
          Issue Type: Improvement
            Reporter: Jun Rao
             Fix For: 0.10.0.0


Currently, ControlledShutdownLeaderSelector selects an arbitrary in-sync replica as the new leader. This means that leader can change again to the preferred replica very quickly. It's better for ControlledShutdownLeaderSelector to select the preferred replica as the new leader, if it's in sync.
