[jira] [Created] (YARN-9490) applicationresourceusagereport return
wrong number of reserved containers
yanbing zhang created YARN-9490:
-----------------------------------
Summary: applicationresourceusagereport return wrong number of reserved containers
Key: YARN-9490
URL: https://issues.apache.org/jira/browse/YARN-9490
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Affects Versions: 3.3.0
Reporter: yanbing zhang
Fix For: 3.3.0
when getting an ApplicationResourceUsageReport instance from the class of SchedulerApplicationAttempt, I found the input constructor parameter(reservedContainers.size()) is wrong. because the type of this variable is Map<SchedulerRequestKey, Map<NodeId, RMContainer>>, so "reservedContainer.size()" is not the number of containers, but the number of SchedulerRequestKey.
