Elliott Clark commented on HBASE-8580:
--------------------------------------
Yes there is no guarantee that things won't degrade. But before we move files
in from tmp we should know that they were on 3 datanodes at least when we did
the move.
Mostly this came from a user in #hbase irc. He was seeing hfile corruption
when region servers were crashing on heavy compactions.
> Ensure that there are 3 replicas when Flushing or Compacting

> 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.
