produces wrong schema
Flattening of bags with unknown schemas produces wrong schema
-------------------------------------------------------------
Key: PIG-1627
URL: https://issues.apache.org/jira/browse/PIG-1627
Project: Pig
Issue Type: Bug
Components: impl
Affects Versions: 0.7.0
Reporter: Alan Gates
Assignee: Alan Gates
Fix For: 0.9.0
The following should produce an unknown schema:
{code}
A = load '/Users/gates/test/data/studenttab10';
B = group A by $0;
C = foreach B generate flatten(A);
describe C;
{code}
Instead it gives
{code}
C: {bytearray}
{code}

[jira] Commented: (PIG-1627) Flattening of bags with unknown
schemas produces wrong schema

Alan Gates commented on PIG-1627:
---------------------------------
The problem is in the flatten, not the group. The group has the proper schema (bytearray, bag{}). Loading a bag of unknown schema and flattening it produces the same result.
Flattening a tuple of unknown content has the same problem as well.
