Subject Re: What's the basic idea of pseudo-distributed Hadoop ?

Hey, Kai

Thanks for you reply.

I was wondering what's difference btw the pseudo-distributed and
fully-distributed hadoop, except the maximum number of map/reduce.

And if a MR program works fine in pseudo-distributed cluster, will it work
exactly fine in the fully-distributed cluster ?
