For those of you that are interested in Hadoop cluster multi-tenacy for Apache Spark, you might have heard about Apache Livy. If you go to the Apache Livy documentation site, it’s not very helpful in understanding and seeing the project as a whole, but thankfully there are a couple YouTube videos that were a HUGE help for me. First, I would recommend reading the Apache Livy website, which you might not understand, but it’s okay, it will lay down some information and give you plenty of questions you want answered. Next I would view the next 2 videos. The first video gives a nice overview of Apache Livy. The second video gives a great demo of Apache Livy using Zeppelin, and really does a great job of showing how it will work from a user point of view.
