> when pig script executes "order" before "limit" in spark mode, the results will be wrong.
> cat testlimit.txt
> 1	orange
> 3	coconut
> 5	grape
> 6	pear
> 2	apple
> 4	mango
> testlimit.pig:
> a = load './testlimit.txt' as (x:int, y:chararray);
> b = order a by x;
> c = limit b 1;
> store c into './testlimit.out';
> the result:
> 1	orange
> 2	apple
> 3	coconut
> 4	mango
> 5	grape
> 6	pear
> the correct result should be:
> 1	orange
