Jimmy Xiang commented on HBASE-10101:
-------------------------------------

+1 on v3. For those two failed unit tests, if they are just flaky, I can take a look in HBASE-10090.

bq. We are setting the servername but didn't we just do it up in createOrForceNodeOffline?
createOrForceNodeOffline is just set the info in ZK, not the region states map in the mater.  Actually, this line is not much use, which will removed in in HBASE-10090.

bq. We are doing the above because region could have come from another RS altogether, one that did not get fully processed? Now we force it to be on the current dead server?
We are doing this because the region is transitioning on the new/current dead server now. This happens when the master restarts.  In meta, the region could be still assigned to the old dead server (as recorded in the lastAssignment when the master loads the meta after restart). Since ZK shows the region is already transition on the new dead server, we should not worry about log splitting of the old dead server.  That's why I agree with [~jeffreyz] on clear the last assignment info here.

> Sometimes, I got this test timed out. The log is attached. It could be because the new cluster takes a while to process the dead server, or assign meta.
