Security always played important role in every informational system. For each particular solution before actual implementation we first need to carefully design its protection layers by means of different techniques like authorization, authentication or encryption. But sometimes at the early start developers don’t pay much attention to this topic and concentrate their efforts on the functional aspects of their applications. This is what has happened to Hadoop.
In my previous article about security in world of Big Data I’ve already given a high-level overview of this model. Now I want to share some experience about how to work with Hadoop services on the low level straight from the source code. We will create new principle in Hadoop environment, then we will give him permissions in Ranger and will use him from java application to access the services remotely.
