Ted Yu updated HIVE-8282:
-------------------------
Description:
In convertJoinMapJoin():
{code}
for (Operator<? extends OperatorDesc> parentOp :
joinOp.getParentOperators()) {
if (parentOp instanceof MuxOperator) {
return null;
}
}
{code}
NPE would result if convertJoinMapJoin() returns null:
{code}
MapJoinOperator mapJoinOp = convertJoinMapJoin(joinOp, context,
bigTablePosition);
MapJoinDesc joinDesc = mapJoinOp.getConf();
{code}
