> The {{RowCounter}} in the {{mapreduce}} package uses {{FirstKeyValueMatchingQualifiersFilter}} which was introduced in HBASE-6468. However we do not need that since we match columns in the scan before we filter.
> Deprecate the filter in 2.0 and remove in 3.0.
> Do cleanup of RowCounter that tries to use this filter but actually doesn't.
