> Project: Flink
> Issue Type: Bug
> Components: Runtime / State Backends
> Affects Versions: 1.15.1, 1.16.0

> While enabling compression, Changelog part will wrap output stream using
> StreamCompressionDecorator#decorateWithCompression.
> As the comment said, "IMPORTANT: For streams returned by this method, \{@link
> OutputStream#close()} is not propagated to the inner stream. The inner stream
> must be closed separately.".
> But StateChangeFsUploader will not close inner stream if wrapped stream has
> been closed.
> So the upload may not complete when enabling compression even if it returns
> success.
