Hi, I am not 100% sure it's a bug in AM, but it seems so. I am blacklisting some hosts, which are send through an AllocateRequest in makeRemoteRequest method in RMContainerRequest.java.
However, the blacklist is empty at RM. I traced all over the places where this is lost, and I found that in ApplicationMasterProtocolPBClientImpl.java, in allocate(AllocateRequest request) method, if I print the request.getResourceBlacklistRequest().getBlacklistAdditiions() I see the list, but after it does AllocateRequestProto requestProto = (..).getProto(), and I print the requestProto.getBlacklistRequest().getBlacklistAdditions() now is EMPTY. So basically, AM send an empty black list to RM. I went even further down and traced till YarnServiceProtos.java(in hadoop-yarn-api), but at this point all the logs I have, are removed. it seems this code is regenerated every time I am compiling yarn-api .... Is there something I am missing guys, or is a bug ? Interesting is that release containers list is propagated correctly but I think it comes on other path. I am running hadoop-yarn 2.3. Thanks, robert
