----------------------------
Summary: Potential null deference in
ConvertJoinMapJoin#convertJoinBucketMapJoin()
Key: HIVE-8282
URL: https://issues.apache.org/jira/browse/HIVE-8282
Project: Hive
Issue Type: Bug
Reporter: Ted Yu
Priority: Minor
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}
