-----------------------------------
Is this issue still relevant? I think the current code already checks for a
null bag.

> If a NULL DataBag is passed to org.apache.pig.builtin.TOP then a NPE is
> thrown. Consider:
> {code}
> $: cat foo.tsv
> a {(foo,1),(bar,2)}
> b
> c {(fyha,4),(asdf,9)}
> {code}
> then:
> {code}
> data = LOAD 'foo.tsv' AS (key:chararray, a_bag:bag {t:tuple (name:chararray,
> value:int)});
> tpd = FOREACH data {
> top_n = TOP(1, 1, a_bag);
> GENERATE
> key AS key,
> top_n AS top_n
> ;
> };
> DUMP tpd;
> {code}
> will throw an NPE when it gets to the row with no bag.
