Marcelo Vanzin commented on HIVE-9017:
--------------------------------------

processes. So if one of them just deletes the files, you kinda break the
protocol.

> Currently RSC will leave a lot of temp files in {{/tmp}}, including
> {{*_lock}}, {{*_cache}}, {{spark-submit.*.properties}}, etc.
> We should clean up these files or it will exhaust disk space.
