Cloud Sail Big Data College Hadoop cluster--Machine Information distribution table

1, distributed environment construction
Build a small-scale distributed cluster with 4 machines that install Linux environments.

One of the machines is the master node, the name node, and the other three are the slaver nodes, the data
node. The four machines are connected to each other via routers to experiment with communication and data transmission. All of them
can access the Internet through a router and experiment with the collection of Web documents.

3.1 Hadoop Working cluster
The Hadoop cluster machine is a learning and research use that runs a built-in Hadoop platform and
Run some actual programs.

It's the new Dell with a good machine, and the three slave machines are the old Lenovo that the lab eliminated, with a path
By the device they make up a local area network.

3.2 Hadoop Experimental Cluster
To make it easier for new members to practice Hadoop technology and to prevent the destruction of running programs on actual Hadoop clusters,
So another two old Lenovo computer composition: a "main--tmaster", a "auxiliary--tslave".

This is what the lab Hadoop cluster looks like, though it's simple enough to learn.
