> FileUtil.copy()  relies on IOUtils.copyBytes() to close the incoming streams, which it
does. Normally.
> But if dstFS.create() raises any kind of IOException, then the inputstream "in", which
was created in the line above, will never get closed, and hence be leaked.
>       InputStream in = srcFS.open(src);
>       OutputStream out = dstFS.create(dst, overwrite);
>       IOUtils.copyBytes(in, out, conf, true);
> Some try/catch wrapper around the open operations could close the streams if any exception
gets thrown at that point in the copy process.
