      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.
