Zeppelin makes Big Data Science Easy to Approach

Zero install – Just connect via a web browser and ready to run

Support for multiple execution platforms (Apache Spark, JDBC, Hive…)

Support for multiple languages (Scala, SQL, Python…)

Support for built-in visualizations

Support for reporting

Support for sharing and collaborative work

Does NOT have machine learning built-in – that’s where Apache Spark comes in (or your favorite SQL engine Apache Flink/Drill/Hive… and 30+ others)
