      Description

      MAPREDUCE-861 added support for hierarchical queues and used a new file mapred-queues.xml to configure queues. But the QueueManager will silently skip the file if property "mapred.queue.names" is defined in Configuration. This tripped us when we are testing MAPREDUCE-1235 and copied configuration files from a Hadoop 0.20 cluster.

      I suggest QueueManager issue a friendly warning if both of the following are true: (1) "mapred.queue.names" exists in Configuration; (2) "mapred-queues.xml" is found in the classpath.
