dalongliu updated FLINK-14055:
------------------------------
Release Note:
In 1.16, we introduced the `CREATE FUNCTION ... USING JAR` syntax to support
the dynamic loading of the UDF jar in per job, which is convenient for platform
developers to easily achieve UDF management. In addition, we also port the `ADD
JAR` syntax from SqlClient to `TableEnvironment` side, this allows the syntax
is more general to Table API users. However, due to inconsistent classloader in
StreamExecutionEnvironment and TableEnvironment, the `ADD JAR` syntax is not
available for Table API program currently, it will be resolved by
https://issues.apache.org/jira/browse/FLINK-29240.
More information about this feature could be found in
https://nightlies.apache.org/flink/flink-docs-master/docs/dev/table/sql/create/#create-function.
