I think this may be fixed by MAPREDUCE-2372.

> 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.
