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

             Summary: HA as a general YARN service to highlighted container by application.
                 Key: YARN-4601
                 URL: https://issues.apache.org/jira/browse/YARN-4601
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: applications
            Reporter: Junping Du
            Assignee: Junping Du
            Priority: Critical


For LRS (long running services) on YARN, get rid of single point failure for critical container
failure may not be necessary. Some applications would like to build its own HA architecture.
However, it would be ideal to provide some fundamental support to HA service in YARN, like:
launching container marked with active/standby, monitor/trigger out failed over, provide end
point for shring information between active/standby container, etc.
