Up to you Lars.  I think the story will be cleaner if its done in 0.21
since whats in 0.20 basically works and since the new thrift is a
radical break

As I see it, TRUNK (hbase 0.21) is for the big, destabilizing changes:
master rewrite, maven, new thrift, etc.  The revival of hbase 0.20
branch is to keep those who are hunkering down on hadoop 0.20 happy (A
good few users will probably stick with hadoop 0.20 a while given
whats going on up in the parent project -- see hadoop general for
discussion -- and even more so if there is the possibility of a
working flush/sync patch for an hdfs 0.20).  So, IMO, backporting
bug-fixes and critical features only makes sense on hbase 0.20 branch.
and the thrift redo should go on in TRUNK.
