[VOTE] Commit hdfs-1024 to 0.20 branch
Stack 2010-04-02, 17:38
Please on committing HDFS-1024 to the hadoop 0.20 branch.

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
