> 'cp' (copy) command doesn’t work with hdfs-fuse file system. It works by passing 'cp' command two times for the same file. It mainly happens when destination file doesn’t exists. It happens because when 'cp' command is performed for the first time it creates the file at the destination path, but as per ozone file system protocols any file has no access till its committed. So, 'getattr' function is not able to locate the file(though it’s present at the destination path). Hence, 'cp' command fails in the first go. Second time when 'cp' command is executed, file is already present in the destination path so 'cp' command simply override the data in the file.
