Wechar reassigned HIVE-26259:
-----------------------------
> Alter Function does not update resource uris
> --------------------------------------------
>
> Key: HIVE-26259
> URL: https://issues.apache.org/jira/browse/HIVE-26259
> Project: Hive
> Issue Type: Bug
> Components: Hive
> Affects Versions: 3.1.2
> Reporter: Wechar
> Assignee: Wechar
> Priority: Major
> Fix For: 4.0.0-alpha-2
>
>
> *Bug Description:*
> The jar of Hive permanent UDF can be loaded based on the resource uris, but
> we encountered an issue after changing the resource uris through spark-sql:
> {code:sql}
> CREATE OR REPLACE FUNCTION test_db.test_udf AS 'com.xxx.xxx'
> USING JAR 'hdfs://path/to/jar';
> {code}
> Then when we use the UDF `test_db.test_udf`, an error occured like this:
> {code:sh}
> Error in query: Can not load class 'com.xxx.xxx' when registering the
> function 'test_db.test_udf'...
> {code}
> *Root Cause:*
> Hive metastore does not update resource uris while executing
> `alter_function()`, which should be included and will not make any side
> effect.
