----------------------------------------------
> 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
> Priority: Major
>
> 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.
