Feng Gui commented on SPARK-19779:
----------------------------------
[~srowen] The `Background maintenance` don't clean files started with `temp`, so I think the temp file is not deleted. However, the temp file don't impact to get incorrect results for Structured Streaming Job.

> Project: Spark

> The PR (https://github.com/apache/spark/pull/17012) can to fix restart a Structured Streaming application using hdfs as fileSystem, but also exist a problem that a tmp file of delta file is still reserved in hdfs. And Structured Streaming don't delete the tmp file generated when restart streaming job in future, so we need to delete the tmp file after restart streaming job.
