Marcelo Vanzin commented on SPARK-3090:
---------------------------------------
I think that if we want to add this, it would be better to do so for all modes,
not just yarn-client. Basically have SparkContext itself register a shutdown
hook to shut itself down, and publish the priority of the hook so that apps /
backends can register hooks that run before it (see Hadoop's
ShutdownHookManager for the priority thing - http://goo.gl/BQ1bjk).
That way the code in the yarn-cluster backend can be removed too.
> Avoid not stopping SparkContext with YARN Client mode

> Key: SPARK-3090
> URL: https://issues.apache.org/jira/browse/SPARK-3090
> Project: Spark
> Issue Type: Bug
> Components: Spark Core, YARN
> Affects Versions: 1.1.0
> Reporter: Kousuke Saruta
>
> When we use YARN Cluster mode, ApplicationMaser register a shutdown hook,
> stopping SparkContext.
> Thanks to this, SparkContext can stop even if Application forgets to stop
> SparkContext itself.
> But, unfortunately, YARN Client mode doesn't have such mechanism.
