Building A Hadoop Cluster

I have a post on building a five-node Hadoop cluster using Docker containers:

Notice how 3bd shows up for pretty much all of these services.  This is not what you’d want to do in a real production environment, but because we want to use Docker and easily pass ports through, it’s the simplest way for me to set this up.  If you knew beforehand which node would host which service, you could modify the run.sh batch script that we discussed earlier and open those specific ports.

After assigning masters, we next have to define which nodes are clients in which clusters.
