> 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.
