> When insert Hive Table is finished, it is better to clean out the tmpLocation dir(the
temp directories like ".hive-staging_hive_2017-08-19_10-56-01_540_5448395226195533570-9/-ext-10000"
or "/tmp/hive/..." for an old spark version).
> Otherwise, when lots of spark job are executed, millions of temporary directories are
left in HDFS. And these temporary directories can only be deleted by the maintainer through
the shell script.
