Jonathan Gray commented on HBASE-1605:
--------------------------------------
The 'random' N rows is possible, and what you would get now I think if you just
used the limit filter (you would specify N/M for filter not N if you wanted
total to be N). If you use one mapper, then you get the ordered N rows.
We do lots of OFFSET, LIMIT queries on hbase. The issue is, you must always
run that style query sequentially, especially if you have other filters that
are being called before the paging/limiting filter.
> TableInputFormat should support 'limit'

> Would be useful if TableInputFormat could be passed a 'limit' property value
> that limited the total result set to the value of 'limit'.
