> CopyUtils uses FileUtils.distCp to copy files but doesn't check the return
> value. It returns false if the copy fails.
> Now, REPL LOAD and EXPORT/IMPORT commands internally uses CopyUtils to copy
> data files across clusters and here it may return success even if file copy
> fails and may cause data loss.
> Need to throw error and retry.
