Till Rohrmann created FLINK-19556:
-------------------------------------
Summary:
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: Task
Components: Deployment / YARN
Affects Versions: 1.12.0
Reporter: Till Rohrmann
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}}.
