-----------------------------------

             Summary: Handle coordinator/foreman failures to prevent data loss
                 Key: DRILL-4202
                 URL: https://issues.apache.org/jira/browse/DRILL-4202
             Project: Apache Drill
          Issue Type: Sub-task
            Reporter: Hanifi Gunes
            Priority: Minor


Foreman relies on ephemeral nodes to get rid of zombie profiles. However, foreman failures still cause loss of profile data. This happens at any non-terminal state where profile is not yet persisted. The initial proposal is to rely on watchers to detect state changes and react upon. We can use random back-off or a similar scheme to avoid hammering Zookeeper.
