Alessandro Bellina commented on SPARK-26945:
--------------------------------------------
[~hyukjin.kwon] thanks for taking a look. Seems like q.processAllAvailable is
designed for this use case.
> Python streaming tests flaky while cleaning temp directories after
> StreamingQuery.stop

> Key: SPARK-26945
> URL: https://issues.apache.org/jira/browse/SPARK-26945
> Project: Spark
> Issue Type: Bug
> Components: PySpark
> Affects Versions: 2.4.0
> Reporter: Alessandro Bellina
> Priority: Minor
>
> From the test code, it seems like the `shmutil.rmtree` function is trying to
> delete a directory, but there's likely another thread adding entries to a
> directory, so when it gets to `os.rmdir(path)` it blows up. I think the test
> (and other streaming tests) should call `q.awaitTermination` after `q.stop`,
> before going on. I'll file a separate jira.
