Dan Li commented on PIG-2769:
-----------------------------
It's worth pointing out that Pig 0.9.2 also runs quickly; we only see the
degradation with Pig 0.10.0.
The degradation in performance seems to have a knee as 4 or 5 conditionals
works as expected but as presented, the script takes about 6 minutes at the
GRUNT> prompt after hitting enter; before any Hadoop execution.

> 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
> The pig version we used in the test
> Apache Pig version 0.10.0-SNAPSHOT (rexported)
