The current refresh code is broken with reference to what we want to do long term. We should only change properties of leaf queues. Since we are planning to change the refresh model in MAPREDUCE-893, I think for completeness sake the refresh of the code should build the entire hierarchy, but pickup only leaf level queues and copy properties like acls and state. Currently, since the refresh code is adding to the root queues, hierarchy could be affected which is not in the scope even of MAPREDUCE-893. > 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... For e.g. mapred.queue..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.
