Well, thank you for your interest Vishnu and contributions are very welcome as there so much can be done!
I'll try my best introducing technical part as we do not have that documented yet (BTW that can be a great start to contribute) and patches are welcome. Zeppelin is a standalone Java application with embedded web-server Jetty, it is built by Maven (but hopefully going to switched to Gradle soon) and has a set of shell wrapper scripts to run it under ./bin. It also includes a frontend web application based on Angular.js and built by Grunt under zeppelin-web dir. As Grunt depends on Node.js Maven takes care of installing it in same dir on the "mvn package". Using this web ui zeppelin-server is capable of running notebooks over different "interpreters" with Apache Spark being the most useful right now, so you may think of zeppelin as SparkDriver in terms on architecture. It also includes Spark itself in a local mode, so to start developing or analysing data you do not need to install it separately on your machine. Hope this helps and welcome aboard! -- -- Kind regards, Alexander > On 19 Jan 2015, at 18:50, VISHNU SUBRAMANIAN <[email protected]> > wrote: > > Thanks Alex, > > It worked fine for me.
