Robert Chansler updated HADOOP-5913:
------------------------------------
Release Note: New mradmin command -refreshQueues reads new configuration
of ACLs and queue states from mapred-queues.xml. If the new queue state is not
"running," jobs in progress will continue, but no other jobs from that queue
will be started. (was: Added an ability to stop/start queues. After a queue is
stopped, no jobs can be submitted to the queue, though running jobs will
continue to completion. Added the ability to refresh the state of the queue at
runtime using the 'mapred mradmin -refreshQueues' command. In order to support
the refresh, all queue configuration (including ACLs) is moved to a new
configuration file called mapred-queues.xml. Modified 'mapred queue' commands
and the Web UI to display the queue's state information.)
Editorial pass over all release notes prior to publication of 0.21.
