dalongliu updated FLINK-29240:
------------------------------
Description: Since [FLINK-15635|
https://issues.apache.org/jira/browse/FLINK-15635], we have introduced a user
classloader in table module to manage all user jars, such as the jar added by
`ADD JAR` or `CREATE FUNCTION ... USING JAR` syntax. However, in table API
program user can create `StreamExecutionEnvironment` first, then create
`TableEnvironment` based on it, the classloader in `StreamExecutionEnvironment`
and `TableEnvironment` are not the same. if the user use `ADD JAR` syntax in
SQL query, here maybe occur ClassNotFoundException during compile StreamGraph
to JobGraph because of the different classloader, so we need to unify the
classloader, make sure the classloader is the same.
> Unify the ClassLoader in StreamExecutionEnvironment and TableEnvironment
