-------------------------------

[~churromorales]

I understood the your point. However this is an api exposed to client side and it ll be better if we do it clean. Otherwise once its released, we have to support the same for future version till we can deprecate it with a major version.

The change suggested here is not very major, rather {{QueueConfigurations}} will be similar to {{MaxAMPercentage}} class in the patch. It should be pretty straight forward as per me.

> `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.
