-------------------------------------
One of the earlier comments from Hemanth also seems to be missing in the latest
patch.
bq. 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

> 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.
