[~straw] It may seem like class conflict as the [flink-sql-connector-hive.jar|http://example.com] does contain the class.  


was (Author: luoyuxia):
[~straw]  I download the [flink-hive-connector |[Download|https://repo.maven.apache.org/maven2/org/apache/flink/flink-sql-connector-hive-2.3.6_2.11/1.14.2/flink-sql-connector-hive-2.3.6_2.11-1.14.2.jar]]
