Thanks Chia-Ping Tsai and Sean Busbey for the inputs. Looks like we need to
keep both versions.

So long as we're still supporting integration with the Apache Hadoop
MapReduce project including versions that have both the old and new
api, I think we need to support both.

Thanks for bringing this up Chia-Ping Tsai. Yes, the question can be more
general whether we need to support the old API.

Re: [DISCUSS] RowCounter duplication

There are other tools having two versions - o.a.h.h.mapreduce and o.a.h.h.mapred
It seems to me the question is "should hbase support old MR APIs ?' Given that 
hadoop 3.0 doesn't mark old MR APIs deprecated, we should keep them in hbase? 
Or we can deprecate them in hbase-2+ in order to remove them in the future?

[DISCUSS] RowCounter duplication

[Peter Somogyi]

Hi,

Currently we have 2 RowCounter tools in our
repository: o.a.h.h.mapreduce.RowCounter and o.a.h.h.mapred.RowCounter.
None of them is marked as deprecated but mapred.RowCounter was deprecated
in pre-HBase 1 releases and the annotation was eventually removed
in HBASE-11178.

Do we still want to or need to keep both versions? The mapred tool is not
documented in refguide and the command's usage is minimal. The
mapreduce.RowCounter tool also has more features.

Thanks,
Peter
