          Since almost the entire patch in HADOOP-4257 should be committed to 0.18, I will re-open HADOOP-4257, instead of fixing here.

          +1. This looks good.

          One suggestion is that DataNode should not only validate the meta information but also the integrity of block content before participating in a recovery process.
