-------------------------------
Summary: FSAppAttempt adds duplicate ResourceRequest to demand in
updateDemand.
Key: YARN-4979
URL: https://issues.apache.org/jira/browse/YARN-4979
Project: Hadoop YARN
Issue Type: Bug
Components: fairscheduler
Affects Versions: 2.7.2, 2.8.0
Reporter: zhihai xu
Assignee: zhihai xu
FSAppAttempt adds duplicate ResourceRequest to demand in updateDemand. We
should only count ResourceRequest for ResourceRequest.ANY when calculate demand.
Because {{hasContainerForNode}} will return false if no container request for
ResourceRequest.ANY and both {{allocateNodeLocal}} and {{allocateRackLocal}}
will also decrease the number of containers for ResourceRequest.ANY.
This issue may cause current memory demand overflow(integer) because duplicate
requests can be on multiple nodes.
