------------------------------------

             Summary: Fix Templeton map-only tasks are getting killed after 10 minutes by
MapReduce
                 Key: HIVE-4755
                 URL: https://issues.apache.org/jira/browse/HIVE-4755
             Project: Hive
          Issue Type: Bug
            Reporter: Shuaishuai Nie


All mapreduce tasks are supposed to report progress back to MR framework, otherwise, if there
is no progress in 10 minutes (by default), TT will kill the task.
Templeton map-only task has a KeepAlive thread that is supposed to periodically report the
progress and keep the launcher alive, however this does not seem to work as expected.
