Description

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).
