Vinod K V commented on MAPREDUCE-861: ------------------------------------- With this patch, old capacity-scheduler specific queue configuration in capacity-scheduler.xml will no longer work. Will we provide backward compatibility or will this be an incompatible change w.r.t those config items? > 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 > Assignee: rahul k singh > Attachments: MAPREDUCE-861-1.patch, MAPREDUCE-861-2.patch > > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
