> RM web page shows incorrect max pool size for nested pools
> ----------------------------------------------------------
>                 Key: YARN-5502
>                 URL: https://issues.apache.org/jira/browse/YARN-5502
>             Project: Hadoop YARN
>          Issue Type: Bug
>          Components: fairscheduler, webapp
>    Affects Versions: 2.6.0, 2.7.0
>            Reporter: Tristan Stevens
>         Attachments: yarn-rm.png
> The scheduler page in the webapp incorrectly shows child pools' maximum sizes without
first considering the maximum size of the parent.
> For example:
> Parent Queue AppD has Weight 100, Max: 1 CPU 100MB RAM
> Child Queue AppD.Child2 has Weight 1 Max: 100 CPU 1PB RAM
> In YARN RM, the max resources for AppD.Child2 shows up as being larger than the max resources
for AppD, although the execution in the scheduler here is actually fine. In the image attached
AppE has the same maximum as AppD, yet AppD.Child2 shows as having Max Resources well above
that of AppE.
