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
> Projections in nested filter and inside foreach do not work

> 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';
