> When SGP perform recover process, it new a RestorableTsFileIOWriter for each tsfile. However, it doesn't close the writer after using it. !screenshot-1.png!  So the output stream to the file will be kept in process. When recovering compaction, if the system tries to delete a tsfile, exception will occur because the handler of the file isn't removed. !screenshot-2.png!
