Jesus Camacho Rodriguez created HIVE-22219:
----------------------------------------------

             Summary: Bringing a node manager down blocks restart of LLAP service
                 Key: HIVE-22219
                 URL: https://issues.apache.org/jira/browse/HIVE-22219
             Project: Hive
          Issue Type: Bug
          Components: llap
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez


For YARN service, when number of running instances != number of desired instances, the service state may be in STARTED or FLEX (instead of STABLE). For Hive LLAP side, there is a config to control the threshold of service health check. The Hive LLAP code misses checking these states, which can result in the service not coming up even if the threshold is met.
