@gatorsmile hiï¼spark just suport HIVE UDF which resources is in the local
disk, or spark-sql --jars xxx.jar or something else. But I think spark don't
support the hive permanent function which resources are in hdfs.
CREATE FUNCTION hdfs_udf AS 'xxx.udf' USING JAR
'hdfs://<defaultFS>/user/udf/<hive-udf>.jar';
My pr just download the hdfs resources and add to the classpath.
