Apache Zeppelin and Spark are turning out to be useful tools in the toolkit of the modern data scientist when working on large scale datasets for machine learning. Zeppelin makes Big Data accessible with minimal effort using web browser based notebooks to interact with data in Hadoop. It enables data scientists to interactively explore and visualize their data and collaborate with others to develop models. Zeppelin has great integration with Apache Spark that delivers many machine learning algorithms out of the box to Zeppelin users as well as providing a fast engine to run custom machine learning on Big Data. The talk will describe the latest in Zeppelin and focus on how it has been made ready for the enterprise. With support for secure Hadoop clusters, LDAP/AD integration, user impersonation and session separation, Zeppelin can now be confidently used in secure and multi-tenant enterprise domains.
