> Affects Versions: 2.0.0
> Reporter: Lars George
> Assignee: Abhishek Singh Chouhan
> Priority: Minor
> Fix For: 2.0.0, 1.3.0

>
> 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.
