Subject [jira] Commented: (HBASE-3243) Disable Table closed region on wrong host

Todd Lipcon commented on HBASE-3243:
------------------------------------

Thanks for looking at this, Jon. I can run some tests with my "crazy config" which generates
lots and lots of regions, and see if it happens again. Any good log messages you can suggest
adding for this test?

> I ran some YCSB benchmarks which resulted in about 150 regions worth of data overnight.
Then I disabled the table, and the master for some reason closed one region on the wrong server.
The server ignored this, but the region remained open on a different server, which later flipped
out when it tried to flush due to hlog accumulation.
