Modify queue configuration format and parsing to support a hierarchy of queues.
-------------------------------------------------------------------------------
Key: MAPREDUCE-861
URL: https://issues.apache.org/jira/browse/MAPREDUCE-861
Project: Hadoop Map/Reduce
Issue Type: Sub-task
Reporter: Hemanth Yamijala
MAPREDUCE-853 proposes to introduce a hierarchy of queues into the Map/Reduce
framework. This JIRA is for defining changes to the configuration related to
queues.
The current format for defining a queue and its properties is as follows:
mapred.queue.<queue-name>.<property-name>. For e.g.
mapred.queue.<queue-name>.acl-submit-job. The reason for using this verbose
format was to be able to reuse the Configuration parser in Hadoop. However,
administrators currently using the queue configuration have already indicated a
very strong desire for a more manageable format. Since, this becomes more
unwieldy with hierarchical queues, the time may be good to introduce a new
format for representing queue configuration.
