A Herd of Elephants - Navigating the Hadoop Ecosystem

Vinayak Hegde


A overview of the Hadoop ecosystem and how the different parts of the ecosystem interact and fit together.


Hadoop has matured to point where it is not longer just one project but a bunch of projects ranging from getting data onto the cluster to processing and analyzing data to managing the cluster itself. I will be talking from my personal experiences from setting up a hadoop cluster at Inmobi that processes 10TB+ of Data per day (and growing). The several Hadoop clusters in Inmobi are spread over multiple datacenters across continents.

Projects that will be covered in some detail include Hadoop (HDFS and Mapreduce), Hive, HBase, Pig, Mahout, Scribe , Zookeeper and Oozie/Azkhaban.


Should have basic familiarity with Hadoop.
