----------------------------
Resolution: Duplicate
> Add log messages for jobs in ACCEPTED state but not runnable.
> -------------------------------------------------------------
>
> Key: YARN-5563
> URL: https://issues.apache.org/jira/browse/YARN-5563
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: fairscheduler
> Reporter: Yufei Gu
> Assignee: Yufei Gu
> Labels: supportability
>
> Leaf queues maintain a list of runnable and non-runnable apps. FairScheduler
> marks an app non-runnable for different reasons: exceeding the following
> properties of the leaf queue:
> (1) queue max apps,
> (2) user max apps,
> (3) queue maxResources,
> (4) maxAMShare.
> It would be nice to log the reason an app isn't runnable. The first three are
> easy to infer, but the last one (maxAMShare) is particularly hard. We are
> going to log all of them and show the reason if any in WebUI application view.
