NullPointerException for hadoop clients launched from streaming tasks

          Description

          TaskRunner sets HADOOP_ROOT_LOGGER to info,TLA while launching the child tasks. TLA implicitly assumes that that task-id information will be made available via the 'hadoop.tasklog.taskid' parameter. 'hadoop.tasklog.taskid' is passed to the child task by the TaskRunner via HADOOP_CLIENT_OPTS. When the streaming task launches a hadoop client (say hadoop job -list), the HADOOP_ROOT_LOGGER of the hadoop client is set to 'info,TLA' but hadoop.tasklog.taskid is not set resulting into NPE.

            Attaching a patch for Yahoo!'s distribution if Hadoop not to be committed here. This patch adds HADOOP_CLIENT_OPTS to HADOOP_OPTS so that the TLA level env settings gets passed correctly.

            I think this may be fixed by MAPREDUCE-2372.

            I think this is fixed in branch-1, and is not relevant to other releases.
