Wechar created HIVE-26259:
-----------------------------
Summary: 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
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.
