dianfu opened a new pull request #13436:
URL: https://github.com/apache/flink/pull/13436
## What is the purpose of the change
*Currently, the classes added for Python DataStream is located in
org.apache.flink.datastream and there is already a package named
org.apache.flink.streaming, it would be great to move the these classes to
package org.apache.flink.streaming to be consistent with the naming conversion
of flink-streaming-java. Besides, the class name could also be optimized, e.g.
DataStreamPythonReduceFunctionOperator -> PythonReduceOperator.*
## Brief change log
- *Move classes in org.apache.flink.datastream to
org.apache.flink.streaming*
- *Improve the class names, e.g. DataStreamPythonReduceFunctionOperator ->
PythonReduceOperator, DataStreamPythonPartitionCustomFunctionOperator ->
PythonPartitionCustomOperator*
