> Key: HIVE-20441
> URL: https://issues.apache.org/jira/browse/HIVE-20441
> Project: Hive
> Issue Type: Bug
> Components: CLI, HiveServer2
> Affects Versions: 1.2.1, 2.3.3
> Reporter: Hui Huang
> Assignee: Hui Huang
> Priority: Major
> Fix For: 2.3.3
>
> Attachments: HIVE-20441.1.patch, HIVE-20441.2.patch,

>
> When hive.allow.udf.load.on.demand is set to true and hiveserver2 has been
> started, the new created function from other clients or hiveserver2 will be
> loaded from the metastore at the first time.
> When the udf is used in where clause, we got a NPE like:
> {code:java}

> And the variable registerToSession is true, so the object 'function' will be

> cause the error.
> We should return the result of the method registerToSessionRegistry returned.
