Chris K Wensel commented on HBASE-1605:
---------------------------------------
Nope, doesn't look like it. I'm not calling for a configurable number of
mappers/splits.
But asking the total number of rows returned across all splits be exactly equal
to an optional 'limit' value.
And pointing out the current impl, as I see it in trunk, sets the splits to the
number of regions in a table thus implying that a single global Filter across
all splits won't work as limit may not be evenly divided among the splits.
It will be nice to specify the number of mappers/splits and have it honored
though.
