LOCross output schema is not right
----------------------------------
Key: PIG-290
URL: https://issues.apache.org/jira/browse/PIG-290
Project: Pig
Issue Type: Bug
Components: impl
Affects Versions: types_branch
Reporter: Pi Song
>From the schema generation code:-
{noformat}
List<LogicalOperator> inputs = mPlan.getPredecessors(this);
for (LogicalOperator op : inputs) {
// Create schema here
}
{noformat}
The output schema is generated based on inputs determined in the logical plan.
However, mPlan.getPredecessors() doesn't always preserve the right order (A x
B and B x A result in different schemas). I suggest maintaining mInputs
variable in LOCross (as it used to be) to resolve this issue.
