Configure and Start Apache Knox

When working with the Apache Knox Gateway in your Hadoop cluster, it is important you have the latest version of Knox installed so you can take advantage of new features and enhancements, in addition to ensuring your instance of Knox is in sync with other Hadoop components (e.g., Ranger, Spark, Hive, Hue, etc.) for stability and performance.  For example, if you need to upgrade your Hadoop cluster from 2.2 to 2.5.x, you should also make sure that your individual Hadoop components are also upgraded to the latest version.
