Arun Suresh updated YARN-7173:
------------------------------
Attachment: YARN-7173-branch-2.001.patch
Attaching initial patch. This is intended only for branch-2 - since I guess we
can mandate that upgrades to 3.x should go thru 2.9.0 ?
[~leftnoteasy], do take a look
> Container Update Backward compatibility fix for upgrades from 2.8.x

> 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.
