Koji Noguchi resolved PIG-4968.
-------------------------------
Resolution: Duplicate
This is not a bug in a testcase but bug in pig behavior. Hopefully PIG-4933
would fix it.
[~daijy], please take a look when you have time.
(also, I personally don't like my lengthy patch there. Please take over if
there's a simpler way of fixing it.)

> In jenkins, [it
> |https://builds.apache.org/job/Pig-trunk/1935/#showFailuresLink] shows that
> TestLogicalPlanBuilder#testQuery90 fails. After debugging, it always fails in
> [Line1139
> |https://github.com/apache/pig/blob/trunk/test/org/apache/pig/test/TestLogicalPlanBuilder.java#L1138]
> {code}
> Assert.assertTrue(foreach.getSchema().toString( false
> ).equals("mygroup:tuple(myname:chararray,myage:int),mycount:long"));
> {code}
> The script is
> {code}
> a = load 'myfile' as (name:Chararray, age:Int, gpa:Float);b = group a by
> (name, age);c = foreach b generate group as mygroup:(myname, myage), COUNT(a)
> as mycount;store c into 'output';
> {code}
>
> The reason why fails is because the schema of mygroup(myname,myage) is
> mygroup(myname:bytearray,myage:bytearray) and this user-defined schema is
> assigned to c. so the schema of c is
> not mygroup:tuple(myname:chararray,myage:int) but
> mygroup:tuple(myname:bytearray,myage:bytearray).
> This problem is imported since PIG-2315 as ForEachUserSchemaVisitor is used
> in
> [LogicalPlan|https://github.com/apache/pig/blob/trunk/src/org/apache/pig/newplan/logical/relational/LogicalPlan.java#L179].
