True High Availability for Enterprise Grade Hadoop

Fail-Proofing Hadoop Clusters with Automated Service Failover

With the increase use of Hadoop comes an increase in the need for critical safeguards, especially for the enterprise where any data loss could mean millions in penalties or lost revenue. What happens when parts of an Hadoop cluster goes down? How do Hadoop based solutions cope with NameNode failures? We will share the Hadoop failover issues routinely encountered and best practices for performing continuous health monitoring, full service failover and protecting your cluster from losing data. In addition, we will cover ZooKeeper-based failover for NameNode and other related SPOF services (e.g., JobTracker, Oozie, Kerberos).

Presenter: Jeffery Krone, VP of R&D, Co-founder, Zettaset Inc.

Key Discussion Points:

• Why Name Node Failover is not enough
• Where are the single points of failure and why they are critical
• Preventing data loss
