> it not necessary to do `cleanupTempFiles` while ditcp commit job in direct
> mode, because it there is no temp files in direct mode.
> This clean operation will increase the task execution time, because it will
> get the list of files in the target path. When the number of files in the
> target path is very large, this operation will be very slow.
