Hi Hitesh : Thanks a lot for your reply.
I solved this problem , it is silly mistake. Someone has changed the owner of "/" dir , and according to the errorlog , pdsh need root to proceed. After changing the owner of "/" to root , problem solved. Thank you again for you reply. I have another question. I had a uninstall failure , and there is no button on the website for me to rollback and i don't know what to do about that. What should i do now to reinstall hadoop ?
