Review request for accumulo and Mike Drob.
Bugs: ACCUMULO-2488
https://issues.apache.org/jira/browse/ACCUMULO-2488
Repository: accumulo
Description
-------
The Concurrent randomwalk test used to consider servers unbalanced if any
server's tablet count differed from the cluster average by more than a fifth of
the average or by one, whichever was larger. This would cause failures under
typical balancings from the default balancer.
This commit changes the criterion for an unbalanced server to be double the
standard deviation from the cluster average.
