zhijiangW opened a new pull request #7767: [FLINK-11676][network] Make ResultPartitionWriter extend AutoCloseable
URL: https://github.com/apache/flink/pull/7767
 
 
   ## What is the purpose of the change
   
   *This is a sub-task for refactoring the interface of `ResultPartitionWriter`.*
   
   *We can make `ResultPartitionWriter` extend `AutoCloseable` in order to replace calling `destroyBufferPool` in specific `ResultPartition`. This is a small step for making `Task` reference with general `ResultPartitionWriter` instead of `ResultPartition`.*
   
   ## Brief change log
   
     - *Make `ResultPartitionWriter` extend `AutoCloseable`*
     - *Replace `destroyBufferPool` by close in `ResultPartition`*
     - *Implement empty close methods in other `ResultPartitionWriter` implementations in tests*
   
   ## Verifying this change
   
   *This change is already covered by existing tests.*
