> 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.
