There will be an issue in that the jar we ship with is missing some important fixes that were added to the tip of the append branch (hdfs-1554 and hdfs-1555, utility that hbase needs when splitting logs on node failure). I would suggest you build the tip of the append branch using Michael Noll's instructions. St.Ack
