Yulia,

I just ran "hadoop version" on my NN, separate SNN, and three separate DNs and all point to
the exact  the same build version. I know that you must install the exact same version on
every machine in your cluster to run fully-dist Hadoop.

I have the following error in the cluster:

And all slaves  have

-r 318bc781117fa276ae81a3d111f5eeba0020634f
