--------------------------------------
Hey [~ywskycn],
What about the problem described in YARN-2187 due to maxAMShare enabled by
default ?
> FairScheduler: Update the default value for maxAMShare
> ------------------------------------------------------
>
> Key: YARN-2539
> URL: https://issues.apache.org/jira/browse/YARN-2539
> Project: Hadoop YARN
> Issue Type: Improvement
> Reporter: Wei Yan
> Assignee: Wei Yan
> Priority: Minor
>
> Currently, the maxAMShare per queue is -1 in default, which disables the AM
> share constraint. Change to 0.5f would be good.
