Background: HDFS-1024 fixes possible trashing of fsimage because of failed copy from 2NN and NN. Ordinarily, possible corruption of this proportion would merit commit w/o need of a vote only Dhruba correctly notes that UNLESS both NN and 2NN are upgraded, HDFS-1024 becomes an incompatible change (the NN<->2NN communication will fail always). IMO, this incompatible change can be plastered over with a release note; e.g. WARNING, you MUST update NN and 2NN when you go to 0.20.3 hadoop. If you agree with me, please vote +1 on commit. Thanks, St.Ack
