I check the code again, and a new discovery was synchronized to you @mridulm @Ngone51 The status of `DiskBlockObjectWriter` is lazy initializing, the 'initialize()' method will only be called passively when the `write()` method is called for the first time and set `initialized` as `true`. So in `No writes at all` scene, neither `close()` nor `revertPartialWritesAndClose()` will actually trigger the call of `closeResources()` because `initialized` is false and `revertPartialWritesAndClose()` will truncate an empty file. -- This is an automated message from the Apache Git Service.
