stack commented on HBASE-4842:
------------------------------
bq. The problem is that the RegionState OPENED is reported to the master even
though it may not have written all its new assignment to META yet.
This return is ignored by the master, right? Unless its returning
RegionOpeningState.ALREADY_OPENED?
Should I commit this patch meantime? It seems to make things better for the
moment (Sorry for my being anxious on this one and thanks for working on it
Jon... but I can't build 0.92 locally because of this and I want to cut an RC
-- thanks for the help).

> Its seems that on the 0.92 branch in particular, TestHBaseFsck.testHBaseFsck
> is intermittently failing.
> In the test, a region's assignment is purposely changed in META but not in
> ZK. After the equivalent of 'hbck -fix', a subsequent check that should be
> clean comes up with a new ZK assignment but with META still being
> inconsistent with ZK. The RS in ZK sometimes this points to the same RS, but
> sometimes it "moves" to another ZK.
