> It is possible that datanodes in a DFS pipeline can be dropped.  When this happens it possible for there to be fewer than the number of replicas expected.  After a close on the file the namenode tries to re-replicate the file. On flush and compaction we should block waiting for the number of datanodes reporting that they have the needed blocks to be 3.
