Joe, The dev community is currently gearing up for hadoop-0.23 off trunk.
0.23 is a massive step forward with with HDFS Federation, NextGen MapReduce and possible others such as wire-compat and HA NameNode. In a couple of weeks I plan to create the 0.23 branch off trunk and we then spend all our energies stabilizing & pushing the release out. Please see my note to general@ for more details.
