This seems to have broken working scenarios with Hive MR. We now see
hadoop.tmp.dir is always set to /tmp/hadoop-hive (in job.xml). This creates
problems on a multi-tenant hadoop cluster since ownership of tmp folder is set
to the user who executes the jobs first and other users fails to write to tmp
folder.
E.g. User1 run job and /tmp/hadoop-hive is created on worker node with
ownership to user1 and sibsequently user2 tries to run a job and job fails due
to no write permission on /tmp/hadoop-hive/
Old behavior allowed multiple tenants to write to their respective tmp folders
which was secure and contention free. User1 - /tmp/hadoop-user1, User2 -
/tmp/hadoop-user2.
