Chandni Singh reassigned YARN-9071:
-----------------------------------
Assignee: Chandni Singh
> NM and service AM don't have updated status for reinitialized containers
> ------------------------------------------------------------------------
>
> Key: YARN-9071
> URL: https://issues.apache.org/jira/browse/YARN-9071
> Project: Hadoop YARN
> Issue Type: Bug
> Reporter: Billie Rinaldi
> Assignee: Chandni Singh
> Priority: Critical
>
> Container resource monitoring is not stopped during the reinitialization
> process, and this prevents the NM from obtaining updated process tree
> information when the container starts running again. I observed a
> reinitialized container go from RUNNING to REINITIALIZING to
> REINITIALIZING_AWAITING_KILL to SCHEDULED to RUNNING. Container monitoring
> was then started for a second time, but since the trackingContainers entry
> had already been initialized for the container, ContainersMonitor skipped
> finding the new PID and IP for the container. A possible solution would be to
> stop the container monitoring in the reinitialization process so that the
> process tree information would be initialized properly when monitoring is
> restarted. When the same container was stopped by the NM later, the NM did
> not kill the container, and the service AM received an unexpected event (stop
> at reinitializing).
