Hello all,
I installed hadoop0.20.2 on physical machines and everything works like a c=
harm. Now I installed hadoop using the same hadoop-install gz file on the c=
loud. Installation seems fine. I can even copy files to hdfs from master ma=
chine. But when I try to do it from another "non hadoop" machine, I get fol=
lowing error. I did googling and lot of people got this error but could not=
 find any solution.

Also I didn't see any exceptions in the hadoop logs.

Any thoughts?
