--------------------------------------------------------------
Over in HDFS-744 I propose changes to HDFS to allow fsync on files.
Without that both WAL and HFiles (resulting from compactions/flushes) are not
guaranteed to be on disk at the DFS replicas.
The HDFS-744 is becoming big, so I'm not sure how the hadoop folks will receive
it. I any case, this issues tracks the necessary changes on the HBase side.
