rahul k singh updated MAPREDUCE-861: ------------------------------------ Release Note: Added support for hierarchical queues in the Map/Reduce framework with the following changes: - mapred-queues.xml is modified to a new XML template as mentioned in the JIRA. - Modified JobQueueInfo to contain a handle to child queues. - Added new APIs in the client to get 'root' queues, so that the entire hierarchy of queues can be iterated. -Added new APIs to get the child queues for a given queue . was: Added support for hierarchical queues in the Map/Reduce framework with the following changes: - mapred-queues.xml is modified to a new XML template as mentioned in the JIRA. - Modified JobQueueInfo to contain a handle to child queues. - Added new APIs in the client to get 'root' queues, so that the entire hierarchy of queues can be iterated. > 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 > Components: jobtracker > Reporter: Hemanth Yamijala > Assignee: rahul k singh > Fix For: 0.21.0 > > Attachments: MAPREDUCE-861-1.patch, MAPREDUCE-861-2.patch, > MAPREDUCE-861-3.patch, MAPREDUCE-861-4.patch, MAPREDUCE-861-5.patch, > MAPREDUCE-861-6.patch, MAPREDUCE-861-7.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.
