Subject [jira] [Created] (YARN-1443) blacklist is not propagated from AM to RM
Date Mon, 25 Nov 2013 19:30:35 GMT
Robert Grandl created YARN-1443:
-----------------------------------

             Summary: 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
