> We need to port forward the patch over in hbase-2234 that was added to 
> branch.  I've made the task a blocker against 0.21.  Porting forward is a 
> little awkward at the moment since the patch as is depends on hdfs-200 which 
> is not currently in hbase TRUNK (HBase TRUNK has hadoop 0.21 as opposed to 
> hadoop 0.20 in it).   Chatting yesterday with a few of the lads, hbase-2255 
> "Take trunk back to hadoop 0.20" might make sense in the near term -- to be 
> further discussed out on the list -- and if so, the forward port will be 
> straight-forward.  Thereafter, we'll have to do some work to make it so 
> hbase-2234 works on top of both hadoop 0.20 and hadoop 0.21 since having 
> hbase run on both hadoop 0.20 and 0.21 is a goal (HBASE-2233).
