Ashutosh Chauhan commented on HIVE-15951:
-----------------------------------------
deleteOnExit() is called when process exists. For container mode, process will
terminate immediately and clean up will happen. For llap, process won't exit
once RecordWriter is done, since its long running process waiting to execute
next query. So, clean up wont happen until llap deamon goes down, which likely
is not useful.
> Make sure base persist directory is unique and deleted
