> But theses commands worked:
> * Absolute path: {{hadoop distcp -update -diff s1 s2 /user/systest/d1
> /user/systest/d2}}
> * No {{-diff}}: {{hadoop distcp -update d1 d2}}
> However, everything was fine when I ran {{hadoop distcp -update -diff s1 s2
> d1 d2}} again. I am not sure the problem only exists with option {{-diff}}.
> Trying to reproduce.
