Re: count function in split statement

[Johannes Zillmann]

Ok, discovered that i have to use "count" in upper-case.
Then it works!

Hi there,

just wondering if something like this is/should be possible ? :
A=
(a, {(a, 1), (a, 2), (a, 3)})
(a, {})
split A into B if (count($1)==3), C;

Trying this gives me an exception:
Caused by: org.apache.pig.impl.logicalLayer.parser.ParseException:
