Bikas Saha commented on YARN-1443:
----------------------------------
Are you using AMRMClient/AMRMClientAsync or writing against the protocol API's
directly? If its the later, then can you please try using the AMRMClient
libraries. If the issue does not repro with the client libraries then it could
be a bug in your code.
> blacklist is not propagated from AM to RM

> Key: YARN-1443
> URL: https://issues.apache.org/jira/browse/YARN-1443
> Project: Hadoop YARN
> Issue Type: Bug
> Components: api, client
> Reporter: Robert Grandl
> Priority: Minor
>
> 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
