Till Rohrmann commented on FLINK-19556:
---------------------------------------
Alright, thanks for the information [~karmagyz] and [~xintongsong]. Then let's
try to properly fix the problem in FLINK-19324. Once FLINK-19324 is closed, we
can close this issue here as well. I will add a link to remind us of that.
> YarnResourceManagerDriver.getPendingRequestsAndCheckConsistency only returns
> container requests for first matching equivalent resource

> Key: FLINK-19556
> URL: https://issues.apache.org/jira/browse/FLINK-19556
> Project: Flink
> Issue Type: Bug
> Components: Deployment / YARN
> Affects Versions: 1.12.0
> Reporter: Till Rohrmann
> Priority: Major
> Fix For: 1.12.0
>
>
> The {{YarnResourceManagerDriver}} will retrieve the number of pending
> container requests for a given {{Resource}} by calling
> {{YarnResourceManagerDriver.getPendingRequestsAndCheckConsistency(Resource)}}.
> Part of this method is to find the equivalent resources for the given
> resource. Next we find for every equivalent resource the matching container
> requests. Instead of unifying these collection of container requests, the
> method returns the first non-empty collection. This might return an
> incomplete set of container requests if the Yarn respects the vcores of
> resources given to {{AMRMClientAsync.getMatchingRequests}}.
