Summary: When using pig with HBaseStorage, pig filters should utilize hbase
indexes to limit workset. (was: When using pig with hbase, pig filters should
utilize hbase indexes to limit workset.)

>
> The LOAD function using HBaseStorage has filter arguments you can use limit
> the working set for an MR job.
> e.g.
> blah = LOAD 'hbase://test' using
> org.apache.pig.backend.hadoop.hbase.HBaseStorage('cf:field1', '-loadKey -gte
> foo1 -lte foo1');
> It would be really great if this could also be applied to filter statements
> within pig, where a filter statement within pig e.g.
> blah2 = FILTER blah by key=foo1; or
> blah2 = FILTER blah by key > foo1 and key < foo2;
> would actually limit what is retrieved from hbase, so big has a smaller
> working set to perform MR on.
