Hortnworks Zeppelin Notebook for Dummies by Salil Mehendale
What is Zeppelin?
A completely open web-based notebook that enables
interactive data analytics
Apache Zeppelin is a new and incubating multi-purposed
web-based notebook which brings data ingestion, data exploration,
visualization, sharing and collaboration features to Hadoop and Spark.
WHAT ZEPPELIN DOES
Interactive browser-based notebooks enable data engineers,
data analysts and data scientists to be more productive by developing,
organizing, executing, and sharing data code and visualizing results without
referring to the command line or needing the cluster details. Notebooks allow
these users not only allow to execute but to interactively work with long
workflows. There are a number of
notebooks available with Spark.
iPython remains a mature choice and great example of a data
science notebook. The Hortonworks
Gallery provides an Ambari stack definition to help our customers quickly set
up iPython on their Hadoop clusters.
Apache Zeppelin is a new and upcoming web-based notebook
which brings data exploration, visualization, sharing and collaboration features
to Spark. It support Python, but also a
growing list of programming languages such as Scala, Hive, SparkSQL, shell and
markdown.
The various languages are supported via Zeppelin language
interpreters.
Data discovery, exploration, reporting and visualization are
key components of the data science workflow.
Zeppelin provides a “Modern Data Science Studio” that supports Spark and
Hive out of the box. Actually, Zeppelin
supports multiple language backends which has support for a growing ecosystem
of data sources. Zeppelin’s notebooks
provides interactive snippet-at-time experience to data scientist. You can see a collection of Zeppelin
notebooks in the Hortonworks Gallery.
Also when you are done with your notebook and found some
insight you want to share, you can easily create a report out of it and either
print it or send it out.
