> Key: SPARK-7930
> URL: https://issues.apache.org/jira/browse/SPARK-7930
> Project: Spark
> Issue Type: Bug
> Components: Spark Core, Streaming
> Reporter: Tathagata Das
> Assignee: Tathagata Das
> Priority: Critical
> Fix For: 1.4.0
>
>
> Shutdown hook for temp directories had priority 100 while SparkContext was
> 50. So the local root directory was deleted before SparkContext was shutdown.
> This leads to scary errors on running jobs, at the time of shutdown. This is
> especially a problem when running streaming examples, where Ctrl-C is the
> only way to shutdown.
