Subject Re: MR Job question

In my practice, I define the 'time' as the first part of rowkey, then I can
only process the newly added rows.
I think my practice is not good and not appropriate for other cases, since
the rowkey definition is so important.
And I also want to know any good ideas.

Another question is, how can I remove all rows which are inserted three
months ago?
