Thejas M Nair commented on PIG-2135:
------------------------------------
Vivek,
I am unable to reproduce this issue with 0.9, can you please check if the
example in jira description is correct ?
grunt> register filudfs.jar
grunt> a = load 'sample_input' using PigStorage(',') as
(q:chararray,w:chararray);
grunt> b = filter a by org.udfs.Func09('f1',q) == 1 AND org.udfs.Func09('e',w)
== 1 ;
grunt> dump b;
(f1,e)
grunt>
Both expressions are also there in explain plain -

> Pig 0.9 ignoring Multiple filter conditions joined with AND/OR
> ---------------------------------------------------------------
>
> Key: PIG-2135
> URL: https://issues.apache.org/jira/browse/PIG-2135
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.9.0
> Reporter: Vivek Padmanabhan
> Assignee: Thejas M Nair
> Priority: Critical
> Fix For: 0.9.0
>
>
> When I have multiple filter statements joined by AND/OR , except for the
> first condition all other conditions are ignored.
> For example in the below script the second condition (org.udfs.Func09('e',w)
> == 1) is ignored ;
> a = load 'sample_input' using PigStorage(',') as (q:chararray,w:chararray);
> b = filter a by org.udfs.Func09('f1',q) == 1 AND org.udfs.Func09('e',w) ==
> 1 ;
> dump b;
> Output from the script
> (f1,a)
> (f1,e) --> this record should have been filtered by the second condition
> Input for the script;
> f1,a
> f2,b
> f3,c
> f1,e
> f2,f
> f5,e
> The explain of the alias b shows that the second condition is not included in
> the plan itself.
> The above statements works fine with Pig 0.8.
