Koji Noguchi updated PIG-4933:
------------------------------
    Summary: TestDataBagAccess.testBagConstantFlatten1/TestLogicalPlanBuilder.testQuery90  broken after PIG-2315  (was: TestDataBagAccess.testBagConstantFlatten1 broken after PIG-2315)

Found one more test, TestLogicalPlanBuilder.testQuery90, failing.

{code}
a = load 'test3.txt' as (name:chararray, age:int, gpa:float);
b = group a by (name, age);
c = foreach b generate group as mygroup:(myname, myage)
{code} 

Schema for mygroup is becoming (bytearray, bytearray).  

Basically a same pattern from the description when tuple/bag(and probably map) is renamed, it still inserts the casting corrupting the schema.

Two separate issues.
* casts should not be inserted in the first place
* Even if casts are inserted, they shouldn't be casting to "bytearray". 

I'll see if I can work on it next week, but until then trunk is broken for these cases.  If quick fix is needed, we can skip this feature for tuple/map/bag and bring back the previous behavior.    Cc: [~daijy]

Sorry again for not catching these failures before committing the patch.
