> Key: HIVE-15960
> URL: https://issues.apache.org/jira/browse/HIVE-15960
> Project: Hive
> Issue Type: Bug
> Components: llap
> Affects Versions: 2.2.0
> Reporter: Prasanth Jayachandran
> Assignee: Prasanth Jayachandran
>
> AM gets removed from knownAppMasters map when the task count becomes 0. Task
> count becomes 0 during fragment execution as unregisterTask happens when the
> task is actually scheduled to run. This will make umbilical connection to AM
> to be closed. Any new rejections or task kills will have to recreate the
> connection. This can be improved by remove the AM info from knownAppMaster
> after query completion.
