Nandor Kollar commented on PIG-5167:
------------------------------------
[~knoguchi] I see, I think we might not even need Limit_12 Tez-only test case,
but instead, we should add a sort before limit in Limit_5, something like this:
{code}
a = load ':INPATH:/singlefile/studenttab10k';
b = load ':INPATH:/singlefile/votertab10k';
a1 = foreach a generate $0, $1;
b1 = foreach b generate $0, $1;
c = union a1, b1;
d = order c by $0;
e = limit d 100;
store e into ':OUTPATH:';
{code}
What do you think? Maybe this is not the best option regarding performance
though.
> Limit_4 is failing with spark exec type
