------------------------------------------------
[~anoop.hbase] All the tests (including existing RowCounter Tests) passed. Mind
taking a look at the patch?

> The {{RowCounter}} in the {{mapreduce}} package is supposed to check if the
> row count scan has a column selection added to it, and if so, use a different
> filter that finds the row and counts it. But the {{qualifier.add()}} call is
> missing in the {{for}} loop. See
> https://github.com/apache/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/mapreduce/RowCounter.java#L165
> Needs fixing or row count might be wrong when using {{--range}}.
