Varun Saxena commented on YARN-3946:
------------------------------------
I hope the intention is primarily debugging and not some other use case, where
a REST API maybe more suitable.
> Allow fetching exact reason as to why a submitted app is in ACCEPTED state.

> URL: https://issues.apache.org/jira/browse/YARN-3946
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: resourcemanager
> Affects Versions: 2.6.0
> Reporter: Sumit Nigam
>
> Currently there is no direct way to get the exact reason as to why a
> submitted app is still in ACCEPTED state. It should be possible to know
> through RM REST API as to what aspect is not being met - say, queue limits
> being reached, or core/ memory requirement not being met, or AM limit being
> reached, etc.
