Subject Backporting HDFS-1620, HDFS-2197, HDFS-2314 to branch-0.23
Date Fri, 09 Sep 2011 03:39:11 GMT
I plan to push the following patches to branch-0.23 tomorrow morning
unless there's any objection:
    HDFS-1620. Rename HdfsConstants -> HdfsServerConstants,
FSConstants -> HdfsConstants. (Harsh J Chouraria via atm)
    HDFS-2197. Refactor RPC call implementations out of NameNode
class. Contributed by Todd Lipcon.
    HDFS-2314. MRV1 test compilation broken after HDFS-2197.
Contributed by Todd Lipcon

The motivation is that the rename in HDFS-1620 touched most of the
files in HDFS and will cause future backports to have a lot of
conflicts unless we backport this one. HDFS-2197 moved all of the RPC
methods out of NameNode.java to a new class, and hence would cause
conflicts on any future changes that affect the NN RPC. 2314 is a
simple bugfix on 2197.

The backports were straightforward so I'll assume it doesn't need a
separate review. If you'd like to take a look, I pushed a tree here:
