FairScheduler after increase number of NM
stefanlee created YARN-8651:
-------------------------------
Summary: We must increase min Resource in FairScheduler after increase number of NM
Key: YARN-8651
URL: https://issues.apache.org/jira/browse/YARN-8651
Project: Hadoop YARN
Issue Type: Bug
Components: fairscheduler
Affects Versions: 2.4.0
Reporter: stefanlee
Nowadays,our cluster has a strange phenomena,before we increase the scale of NodeManager, the resource utilization could be 100%, but we found the resource utilization does not promote as the cluster expansion and many queue's used resource stay at min resource although they have many demand request.
Then we increase their min resource dynamically,the resource utilization of these queues goes up and the resources of the entire cluster are also used after that.
So i doubte if the bug in *FairSharePolicy#compare.*
