I am trying to a limit the output size using LIMIT. I want to the limit
size to be 5 percent of the total output size like this:
-- Put all the inids in a bag so we can count them.
G = GROUP F ALL;
-- Count everything in the bag
H = FOREACH G GENERATE COUNT_STAR(F) AS total;
-- Limit out to 5 percent of the total.
I = LIMIT F H.total * 0.05;
However, when I define the last line with the LIMIT operator, I get the
following error. Does anyone know a way around this?
ERROR 1200: <line 362, column 12> mismatched input 'H' expecting set null
Failed to parse: <line 362, column 12> mismatched input 'H' expecting set
