-------------------------------------------

Hi. Just FYI - I've used Blacklist with Yarn RM 2.2 and 2.3 in 
https://issues.apache.org/jira/browse/TWILL-87 and it seems to work. (i.e. 
blacklist is propagated from AM to RM).

> I was trying to blacklist some nodes. I added a set of hosts as strings into 
> blacklistAdditions list and propagated into 
> RMContainerRequestor#makeRemoteRequest to the RM. 
> However the blacklist is received empty at RM. I logged the path for 
> blacklist in AM and I found that in 
> ApplicationMasterProtocolPBClientImpl#allocate, this list is lost. 
> I print 
> request.getResourceBlacklistRequest().getBlacklistAdditions().toString() at 
> the beginning of ApplicationMasterProtocolPBClientImpl#allocate and the 
> blacklisted additions are there. 
> After AllocateRequestProto requestProto is created based on this request, and 
> I print again 
> requestProto.getBlacklistRequest().getBlacklistAdditionsList().toString(), 
> the blacklist additions is empty now.
> I looked even further and log what happened. At some point in yarn-api, I was 
> lost with my logging as that code was regenerated every time I recompiled 
> yarn-api. 
> Thanks,
> robert
