Review Comment:
@Myasuka, Thanks for your review. Here are my views on these two cases:
> 1. Check the closed flag before createStream to avoid unnecessary
EntropyInjector#createEntropyAware.
If we check `closed` before `createStream`, and the file is being created
when close, we still can't solve the problem. This case usually occurs in
scenarios where the storage system has high latency in creating files.
> 2. What will happen if the stream is closed just after the check if
(closed) in line-463? Will we also have the output stream left over?
If the stream is closed just after the check `if (closed)` in line-463,
output stream can still be closed normally. Because `this.outStream` has been
assigned in line-461, when the `close` method is called, `this.outStream` is
not null, and `this.outStream` and `this.statePath` can be released.
