Summary: ApplicationMasterService#AllocateResponseLock need to hold only ResponseID
Key: YARN-9641
URL: https://issues.apache.org/jira/browse/YARN-9641
Project: Hadoop YARN
Issue Type: Bug
Reporter: Bibin A Chundatt
ApplicationMasterService ApplicationResponseLock could occupy too much memory.
# 5K+ node
# AllocateResponse could contain 5K nodes NodeReport, Container Allocated data too..
Only the responseId is used in ApplicationMaster Service.. No need to hold all the data.
