hbase-4270 IOE ignored during flush-on-close causes dataloss
Review Request #1784 - Created Sept. 9, 2011 and updated
Todd wrote the patch for this issue. Whats posted here is his patch plus a unit test. The diff is pretty big because I refactored the TestOpenRegionHandler so I could share bits of it creating this new TestCloseRegionHandler; the bulk of the patch is making shared mock server and shared mock regionserverservice files.
I ran the new TestCloseRegionHandler test.
