Subject [jira] Updated: (PIG-430) Projections in nested filter and inside foreach do not work
Date Sun, 21 Sep 2008 00:05:44 GMT

     [ https://issues.apache.org/jira/browse/PIG-430?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Santhosh Srinivasan updated PIG-430:
------------------------------------

    Attachment: PIG-430_2.patch

New patch (PIG-430_2.pathc), includes the rewrite of nested projects as foreach generates
for the nested sort, nested distinct and nested filter inputs. Shravan's patch is included
as part of this patch. His patch for fixing the BracketedProject projection was fine. Thanks
Shravan!

Unit tests that still fail are:

    [junit] Running org.apache.pig.test.TestEvalPipeline
    [junit] Tests run: 8, Failures: 1, Errors: 0, Time elapsed: 175.711 sec
    [junit] Test org.apache.pig.test.TestEvalPipeline FAILED

> The following queries do not work:
> Nested filter:
> a = load 'studenttab10k' as (name, age, gpa);
> b = filter a by age < 20;
> c = group b by age;
> d = foreach c { cf = filter b by gpa < 3.0; cp = cf.gpa; cd = distinct cp; co = order
cd by $0; generate group, flatten(co); }
> store d into 'output';
> Nested Distinct:
> a = load '/user/pig/tests/data/singlefile/studenttab10k' as (name, age, gpa);
> b = group a by name;
> c = foreach b { aa = distinct a.age; generate group, COUNT(aa); }
> store c into 'output';
