Subject [jira] [Commented] (PIG-2769) a simple logic causes very long compiling time on pig 0.10.0
Date Wed, 11 Jul 2012 18:23:35 GMT

    [ https://issues.apache.org/jira/browse/PIG-2769?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13411811#comment-13411811
] 

Daniel Dai commented on PIG-2769:
---------------------------------

No, it is not fixed. 5 min to compile a plan is not acceptable. I am not saying a particular
version works, just to post what I observe. Sorry for the confusion. We need to fix it.

> 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)
