Arun Suresh commented on YARN-5221:
-----------------------------------
Thanks for the review [~leftnoteasy]
bq. How to handle container version mismatch issue or other issues which cause
update failure?
In the patch, the checking is done in the {{ApplicationMasterService}} and it
just logs the mismatch. I agree, let me update the {{AllocateResponse}} to
include something like failed update requests (with a message giving the reason)
bq. org.apache.hadoop.yarn.server.resourcemanager.scheduler.Allocation: should
we merge increase/decrease container list ?
We could, but since that is not part of the API per se I was thinking that
maybe its fine as it is.. we can probably file a follow-up JIRA
I agree with the rest of your comments... will update the patch shortly
addressing them.
