Subject [jira] [Commented] (PIG-2385) Store statements not getting processed
Date Mon, 05 Dec 2011 18:52:40 GMT

    [ https://issues.apache.org/jira/browse/PIG-2385?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13162943#comment-13162943

Daniel Dai commented on PIG-2385:

Hi, Olga, the conditions are:
1. Use scalar
2. Multiple stores in script
3. Muti-query is off, or the multi-query is on, but you have "exec" in the middle of script(the
script before exec contains scalar definition)

When this happens, Pig does not even create empty directory.

>          Issue Type: Bug
>    Affects Versions: 0.9.1
>            Reporter: Vivek Padmanabhan
>            Assignee: Daniel Dai
>            Priority: Critical
>             Fix For: 0.10, 0.9.2, 0.11
>         Attachments: PIG-2385-0.patch, PIG-2385-1.patch
> The actual script in which we got this issue is pretty big and complex. The script has
total 4 STORE statements and one of the STORE statement is not getting executed.
> The script executes 3 sets of jobs (excluding one STORE which is not getting executed)
consisting of 10, 11 and 19 jobs.
> The below script could be used to illustrate the issue but with Multiquery turned off;
> {code}
> A = LOAD 'input1' as (f1:chararray,f2:chararray,f3:chararray);
> Z = group A all;
> Z1 = foreach Z generate COUNT(A) as count;
> B = foreach A generate f1,f2,f3,(100-Z1.count) as diff;
> C = order B by diff;
> STORE C INTO 'output/C_out';
> store D into 'output/F_out';
> {code}
> For this script, if run with Multiquery turned off, the Store command for D is not getting
> I can see that the statements are getting parsed and LOStore created for D , but still,
it is not getting executed.
> The above script works fine with Pig 0.8.(This issue still exists in Trunk as well)
