[jira] [Created] (HIVE-19202) CBO failed due to NullPointerException in HiveAggregate.isBucketedInput()

zhuwei created HIVE-19202:
-----------------------------

             Summary: CBO failed due to NullPointerException in HiveAggregate.isBucketedInput()
                 Key: HIVE-19202
                 URL: https://issues.apache.org/jira/browse/HIVE-19202
             Project: Hive
          Issue Type: Bug
            Reporter: zhuwei
            Assignee: zhuwei


I ran a query with join and group by with below settings, COB failed due to NullPointerException in HiveAggregate.isBucketedInput()

set hive.execution.engine=tez;

set hive.cbo.costmodel.extended=true;

 

In class HiveRelMdDistribution, we implemented below functions:

public RelDistribution distribution(HiveAggregate aggregate, RelMetadataQuery mq)

public RelDistribution distribution(HiveJoin join, RelMetadataQuery mq)

 

But in HiveAggregate.isBucketedInput, the argument passed to distribution is "this.getInput()"

, obviously it's not right here. The right argument needed is "this"
