> AliyunOSSBlockOutputStream buffers data in local directory before uploading
> to OSS. It uses LocalDirAllocator.createTmpFileForWrite which will create a
> temp file on this directory and invoke DeleteOnExitHook.add to add the path
> to a set and will be deleted on VM exit through a shutdown hook. However, the
> size of set will be growing if the VM does not exit.
