There are many ways to deploy your HBase to the cluster. As Hadoop and HBase are written in Java, most of the deployment is done by simply copying all the files to the nodes in the cluster.
The simplest way is to use a script-based approach to sync HBase installation and configurations across the cluster. It may not be as cool compared to other modern deployment management tools, but it works well for small or even medium-sized clusters.
In this recipe, we will create a simple script to sync an HBase installation from its master node to all region servers in the cluster. This approach can be used to deploy Hadoop as well.
Log in to the master node as the user who starts the cluster. We assume that you have set up a non-password SSH from the master node to the region servers, for the user.
