Marco Gaido commented on YARN-8385:
-----------------------------------
Thanks for your answer [~jlowe]. As it is stated in the question on SO
(https://stackoverflow.com/questions/46893123/how-can-i-make-spark-thrift-server-clean-up-its-cache)
I think the application directory is used. I see why the data is not removed
by YARN from you comment above, though. So I think we have to investigate why
Spark is using the application directory in this case. Thanks.

> Key: YARN-8385
> URL: https://issues.apache.org/jira/browse/YARN-8385
> Project: Hadoop YARN
> Issue Type: Bug
> Affects Versions: 2.7.0
> Reporter: Marco Gaido
> Priority: Major
>
> In long running applications, it may happen that many containers are created
> and killed. A use case is Spark Thrift Server when dynamic allocation is
> enabled. A lot of containers are killed and the application keeps running
> indefinitely.
> Currently, YARN seems to remove the local directories only when the whole
> application terminates. In the scenario described above, this can cause
> serious resource leakages. Please, check
> https://issues.apache.org/jira/browse/SPARK-22575.
> I think YARN should clean up all the local directories of a container when it
> is killed and not when the whole application terminates.
