NullPointerException for hadoop clients launched from streaming tasks
---------------------------------------------------------------------
Key: MAPREDUCE-1771
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1771
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: client
Reporter: Amar Kamat
Assignee: Amar Kamat
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.
