---------------------------------------
[~szita]: 1 question about the modification in CombinerOptimizer.java.
{code}
for (PhysicalOperator originalUdfInput :
pplan.getPredecessors(combineUdf).toArray(new PhysicalOperator[0])) {
pplan.trimAbove(originalUdfInput);
pplan.remove(originalUdfInput);
}
{code}
do we really need to change List to Array ?
{code}pplan.getPredecessors(combineUdf).toArray(new PhysicalOperator[0] )){code}
> BugFix e2e tests fail on spark
