> With JVM reuse, TaskRunner.setupWorkDir() lists the contents of workDir and does a fs.delete
on each path listed. If the listed file is a symlink to directory, it will delete the contents
of those linked directories. This would delete files from distributed cache and jars directory,if
mapred.create.symlink is true.
> Changing ownership/permissions of symlinks through ENABLE_TASK_FOR_CLEANUP would change
ownership/permissions of underlying files.
> This is observed by Karam while running streaming jobs with DistributedCache and jvm
reuse.
