Subject Re: Scanner returning subset of data
Date Mon, 08 Apr 2013 21:18:39 GMT
0.92.1 is pretty old. Are you able to deploy newer release, e.g.
and see if the problem can be reproduced ?

Otherwise we have two choices:
1. write a unit / integration test that shows this bug
2. see more of the region server / client logs so that further analysis can
be performed.
