Rohith commented on YARN-3025:
------------------------------
Thanks [[email protected]] for workinig on this jira. I have quick commet on
the patch
The api is introduced is at AMRMClient which used by ApplicationMaster to
connect RM. But this does not retrieve blacklisted nodes from RM which was
already updated on ApplicationMaster failover. From previous discussions, I
believe API is required for retrieving blacklistedNodes from RM.
Am I missing anything?

> We have the following method which updates blacklist:
> {code}
> public synchronized void updateBlacklist(List<String> blacklistAdditions,
> List<String> blacklistRemovals) {
> {code}
> Upon AM failover, there should be an API which returns the blacklisted nodes
> so that the new AM can make consistent decisions.
> The new API can be:
> {code}
> public synchronized List<String> getBlacklistedNodes()
> {code}
