stack commented on HBASE-3996:
------------------------------
bq. @Stack: Could you make sure that your comments are addressed?\
They haven't been. I can't get past the first class. It implements Iterable
but it looks like its also a Collection but doesn't implement Collection
Interfaces and then, it talks about being an Input -- both in the Wrapper class
and the internal TableInputConf (which is a holder for an HTable and a
tablename only... no conf, no input) -- but it has nought to do w/ MR Input.
How we want to proceed? Want me to review fully the last patch put up?
> Support multiple tables and scanners as input to the mapper in map/reduce jobs

> It seems that in many cases feeding data from multiple tables or multiple
> scanners on a single table can save a lot of time when running map/reduce
> jobs.
> I propose a new MultiTableInputFormat class that would allow doing this.
