Eric Badger updated YARN-8744:
------------------------------
Issue Type: Sub-task (was: Improvement)
Parent: YARN-8472
> In some cases docker kill is used to stop non-privileged containers instead
> of sending the signal directly
> ----------------------------------------------------------------------------------------------------------
>
> Key: YARN-8744
> URL: https://issues.apache.org/jira/browse/YARN-8744
> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Chandni Singh
> Assignee: Chandni Singh
> Priority: Major
> Labels: docker
>
> With YARN-8706, stopping docker containers was achieved by
> 1. parsing the user specified {{STOPSIGNAL}} via docker inspect
> 2. executing {{docker kill --signal=<STOPSIGNAL>}}
> Quoting [~ebadger]
> {quote}
> Additionally, for non-privileged containers, we don't need to call docker
> kill. Instead, we can follow the code in handleContainerKill() and send the
> signal directly. I think this code could probably be combined, since at this
> point handleContainerKill() and handleContainerStop() will be doing the same
> thing. The only difference is that the STOPSIGNAL will be used for the stop.
> {quote}
> To achieve the above, we need native code that accepts the name of the signal
> rather than the value (number) of the signal.
