Review comment:
[StreamExecutionEnvironment#getExecutionEnvironment()](https://github.com/apache/flink/blob/master/flink-streaming-java/src/main/java/org/apache/flink/streaming/api/environment/StreamExecutionEnvironment.java#:~:text=public%20static%20StreamExecutionEnvironment%20getExecutionEnvironment()%20%7B)
will load conf to initialize configuration, I have debugged the code, it will
not lead to an empty configuration. On the contrary, getConfiguration() get the
value of
[configuration](https://github.com/apache/flink/blob/master/flink-streaming-java/src/main/java/org/apache/flink/streaming/api/environment/StreamExecutionEnvironment.java#L208),
it is an empty configuration created in
[StreamExecutionEnvironment()](https://github.com/apache/flink/blob/master/flink-streaming-java/src/main/java/org/apache/flink/streaming/api/environment/StreamExecutionEnvironment.java#L221)
