zhijiangW opened a new pull request #8310: [FLINK-12331][network] Introduce partition/gate setup to decouple task registration with NetworkEnvironment
URL: https://github.com/apache/flink/pull/8310
 
 
   ## What is the purpose of the change
   
   *In order to decouple task with `NetworkEnvironment` completely, we introduce interface methods for `InputGate#setup` and `ResultPartitionWriter#setup`. Then the task could call the setup method for the created partitions/gates directly instead of calling current `registerTask` via `NetworkEnvironment`.*
   
   ## Brief change log
   
     - *Introduce `InputGate#setup` and `ResultPartitionWriter#setup` separately*
     - *Refactor the process of setup partition/gate in task to replace `registerTask`*
     - *Refactor the processes of creating `LocalBufferPool` in `SingleInputGate` and `ResultPartition`*
   
   ## Verifying this change
