Assignee: groot
> [Umbrella] Extract and refactor queue resource calculation
> ----------------------------------------------------------
>
> Key: YARN-11300
> URL: https://issues.apache.org/jira/browse/YARN-11300
> Project: Hadoop YARN
> Issue Type: Improvement
> Reporter: András Győri
> Assignee: groot
> Priority: Major
> Labels: newbie, ramp-up
>
> Queue resource calculations are not centralised, scattered through many
> classes and a source of dozens of bugs. We need a common place to store these
> calculations, simplify them if possible and extend it with proper logging.
> Example of such calculations:
> [AbstractLeafQueue#assignContainers|https://github.com/apache/hadoop/blob/3a66348fda29b18054853baed6664fec92dc5cc5/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/src/main/java/org/apache/hadoop/yarn/server/resourcemanager/scheduler/capacity/AbstractLeafQueue.java#L1147]
> [AbstractCSQueue#accept|https://github.com/apache/hadoop/blob/0e6a6d18809c1958e3aaae88f0d3ce5bf380b350/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/src/main/java/org/apache/hadoop/yarn/server/resourcemanager/scheduler/capacity/AbstractCSQueue.java#L1045]
> [AbstractLeafQueue#calculateAndGetAMResourceLimitPerPartition|https://github.com/apache/hadoop/blob/3a66348fda29b18054853baed6664fec92dc5cc5/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/src/main/java/org/apache/hadoop/yarn/server/resourcemanager/scheduler/capacity/AbstractLeafQueue.java#L766]
> [AbstractLeafQueue#updateMaximumApplications|https://github.com/apache/hadoop/blob/3a66348fda29b18054853baed6664fec92dc5cc5/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/src/main/java/org/apache/hadoop/yarn/server/resourcemanager/scheduler/capacity/AbstractLeafQueue.java#L2344]
> ... and many more.
