I have a concern about this change. 1. It is necessary to recycle BufferBuilder in the BufferWritingResultPartition#close method, but not sure why we add `closeBufferPool()` in the `fail` method. 2. Originally, `fail()` is responsible for fail only; `closeNetworkResources` is responsible to close network-related resources after fail() is called. In the `TaskCanceler`, `closeNetworkResources` is called to recycle resources and finally, BufferWritingResultPartition#close() will also be called as well as `closeBufferPool()` in `super.close()`. I am confused why we break this contract and include resource clean-up in fail(), and have to include fail in a cancler? Put in another way, why simply add point 1 is not enough? Let's sync up offline tomorrow. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
