[jira] [Updated] (HIVE-8282) Potential null deference in
ConvertJoinMapJoin#convertJoinBucketMapJoin()
[ https://issues.apache.org/jira/browse/HIVE-8282?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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}
was:
