Koji Noguchi commented on PIG-2769:
-----------------------------------
bq. We should put this into 0.11 branch, maybe there will be an 0.11.2 before
12 comes out.
If we can fix this in 0.11, that would be really nice.
On our clusters, there were multiple users hit with this issue on 0.10.

> 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
> 2
> 3
