> if files in done_intermediate dir were already deleted(deleted manually), not
> move to done dir. Job history will infinitely rename these files later, and
> throw exp always.This will cause newly created files in done_intermediate dir
> can not be moved. Later, when scan done_intermediate dir,
> FileContext.listStatus(done_intermediate) will so slow, and gc problem
