> 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
