Jonathan Hsieh commented on HBASE-4842:
---------------------------------------
Stack.
For now the adding a sleep. Longer term adding some synchronization options
for the open region call or add update the regions state to returning something
like OPENING state and then OPEN state after meta and zk have been updated.

> 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.
