Subject Re: data loss around splits when tserver goes down
Date Tue, 28 Jan 2014 20:34:53 GMT

The issue found in ACCUMULO-2261 should be extremely rare, but should not
cause data loss.

Please let me know if it happens again, or you are seeing any data loss.
 And feel free to post a ticket with any details you can provide.
