Sunil G commented on YARN-6164:
-------------------------------
Thanks [~benson.qiu] for the patch
There are some more high level thoughts after i was checking various CLI and
other PBImpl code.
# We are not sharing per-label Queue resource usage
# We are not sharing per-label Queue configurations (capacity etc).
More or less I am thinking in line of thoughts shared by [~bibinchundatt]
earlier.
bq.Since many informations related to configuration is already exposed by
QueueInfo, Properties may not a become a better logical grouping unless we move
all existing config items to new subclass.
I still kind of feel above statement makes sense. However this is similar to a
problem addressed in {{QueueCapacities}} etc. And in long run, this may be
helpful.
My proposal is something like below.
In {{QueueInfo}}, lets have an api called {{setQueueConfigurations}}. A new
api record could be added named {{QueueConfigurations}} and it can have below
sub items
# capacity
# abs-capacity
# max-capacity
# abs-max-capacity
# max-am-perc
If we have a map in {{QueueInfo}} per-label, then {{QueueConfigurations}} could
be mapped against its accessable-labels.
I would like to have discussion on this approach and we can make it more
generic. [~benson.qiu], [~bibinchundatt] and [~rohithsharma] , thoughts?

> `yarn.scheduler.capacity.maximum-am-resource-percent` is exposed through the
> [Cluster Scheduler
> API|http://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/ResourceManagerRest.html#Cluster_Scheduler_API],
> but not through
> [YarnClient|https://hadoop.apache.org/docs/current/api/org/apache/hadoop/yarn/client/api/YarnClient.html].
> Since YarnClient and RM REST APIs depend on different ports (8032 vs 8088 by
> default), it would be nice to expose `maximum-am-resource-percent` in
> YarnClient as well.
