---------------------------------
Summary: Container Update Backward compatibility fix for upgrades
from 2.8.x
Key: YARN-7173
URL: https://issues.apache.org/jira/browse/YARN-7173
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Arun Suresh
Assignee: Arun Suresh
This is based on discussions with [~leftnoteasy] in YARN-6979.
In YARN-6979, the {{getContainersToDecrease()}} and
{{addAllContainersToDecrease()}} methods were removed from the
NodeHeartbeatResponse (although the actual protobuf fields were still
retained). We need to ensure that for clusters that upgrade from 2.8.x to
2.9.0, the decreased containers should also be sent to the NM.
