The construction of Hadoop cluster environment is a problem that many learners or users of hadoop must face, and there are many blog articles and tutorials about the construction of hadoop cluster environment on the Internet. There is certainly no problem for the master of hadoop, and it can even be said that things are "easy", but for beginners of hadoop, there is a lot of pressure to build a hadoop cluster environment.

There are many articles about the construction of hadoop cluster environment on the Internet, which can be said to be "illustrated". For beginners, even if the steps are more detailed, looking at so many steps, so many instructions will certainly feel very tedious. After all, they all come from rookies step by step. I remember that it was really cumbersome to build a hadoop cluster environment at the beginning.

At present, although there are many commercial distributions of hadoop in China, the construction of cluster environment is basically similar or the same, with many instructions and tedious steps. Sometimes I can't help but wonder why these publishers don't optimize the deployment of hadoop's cluster environment. Fortunately, I finally found a hadoop distribution cluster environment that is easy to build and use.

What is used here is a domestic hadoop release and the DKhadoop launched by Express search. The overall deployment of the cluster environment gives me the impression that it is relatively easy to use and is not as tedious as some previous distributions. Let's take DKhadoop as an example to introduce the construction of this simple and easy-to-use hadoop cluster environment.

1. Customize a name for the cluster: before installing the cluster build, the installer needs to check the environment of the host, DKhadoop needs root permission, and links to the host through ssh.

2. Choose the installation mode. There are three installation modes to choose from, namely, basic installation, full installation and custom installation. The services included in the basic installation are: hafs-2.6.0 installation, JDK1.7.0_79 installation, Yarn-2.6.0 installation and zooleeper-3.4.6 installation.

3. If you choose the full installation mode, there will be more services to be installed. For details, please refer to the figure below and the description section.

4. Custom installation mode can configure roles independently. By testing the performance of the host, DKhadoop will recommend the corresponding allocation settings according to the performance of the host.

5. After selecting an appropriate one from the above three installation modes, click "continue" in the lower right corner to install the build automatically. After the installation of all builds is successful, the deployment of the cluster environment is completed.

The deployment of this set of DKhadoop cluster environment has been optimized and I find it easy to use. Interested friends can go and have a look for themselves!
