Earlier, we were already running Hadoop on a single machine, but we know that Hadoop supports distributed, and its advantage is that it is distributed, so let's take a look at the environment. Here we use a strategy to simulate the environment. We use three Ubuntu machines, one for the master and the other two for the slaver. At the same time, this host, we use the first chapter to build a good environment. We use the steps similar to the first chapter to operate: 1, the operating environment to take ...
