> In the following script:
> {code}
> a = load '1.txt' as (a0, a1);
> b = load '2.txt' as (b0, b1);
> c = join a by a0, b by b0;
> dump c;
> {code}
> If 1.txt is empty, Pig will report
> Successfully read -1 records from: "1.txt"
> In WebUI, we can see we only have one MultiInputCounters: "Input records from
> _0_2.txt". In this case, we should count inputs "1.txt" 0 instead -1.
