[jira] [Created] (YARN-1443) blacklist is not propagated from AM to
RM
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
