>
> 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.
