Subject [jira] Commented: (HBASE-3243) Disable Table closed region on wrong host
Date Mon, 22 Nov 2010 18:08:14 GMT

Jonathan Gray commented on HBASE-3243:
--------------------------------------

Well try running again with my patch.  Or you could even run it again without to see if it
happens again and we could get another set of logs.  I guess run it with the patch and then
if it doesn't ever happen again we can punt the issue or resolve it until we see it again.

> 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.
