Subject [jira] [Commented] (HBASE-16108) RowCounter should support multiple key ranges

Konstantin Ryakhovskiy commented on HBASE-16108:
------------------------------------------------

Should it be applied to both: mapred.RowCounter as well as mapreduce.RowCounter?

> Currently, RowCounter only allows a single key range to be used as a filter. It would
be useful in some cases to be able to specify multiple key ranges (or prefixes) in the same
job. (For example, counting over a set of Phoenix tenant ids in an unsalted table)
> This could be done by enhancing the existing key range parameter to take multiple start/stop
row pairs. Alternately, a new --row-prefixes option could be added, similar to what HBASE-15847
did for VerifyReplication.
