We found the following simple logic will cause very long compiling time for pig
0.10.0, while using pig 0.8.1, everything is fine.
A = load 'A.txt' using PigStorage() AS (m: int);
B = FOREACH A {
days_str = (chararray)
(m == 1 ? 31:
(m == 2 ? 28:
(m == 3 ? 31:
(m == 4 ? 30:
(m == 5 ? 31:
(m == 6 ? 30:
(m == 7 ? 31:
(m == 8 ? 31:
(m == 9 ? 30:
(m == 10 ? 31:
(m == 11 ? 30:31)))))))))));
GENERATE
days_str as days_str;
}
store B into 'B';
and here's a simple input file example: A.txt
1

The pig version we used in the test
