Introducing Apache Zeppelin

Apache Zeppelin is a web-based notebook that enables data-driven, interactive analytics with built-in visualizations. It supports multiple languages with an interpreter framework. Currently, it supports interpreters such as Spark, Markdown, Shell, Hive, Phoenix, Tajo, Flink, Ignite, Lens, HBase, Cassandra, Elasticsearch, Geode, PostgreSQL, and Hawq. It can be used for data ingestion, discovery, analytics, and visualizations using notebooks similar to IPython Notebooks. Zeppelin notebooks recognize output from any language and visualize these using the same tools.

The Zeppelin project started as an incubator project in the Apache software foundation in December 2014 and became a top-level project in May 2016. Zeppelin mainly has four components, as shown in the architecture in Figure 6.3:
