Subject [jira] Commented: (HBASE-3243) Disable Table closed region on wrong host
Date Wed, 17 Nov 2010 05:16:16 GMT

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

No idea if it's related but it seems like AssignmentManager's {{regions}} member is accessed
without synchronization sometimes... could end up getting some incorrect data due to this.

> 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.
