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

== UPDATE ==
I am sorry to announce that we've had some last minute changes and you will need to re-register for tonight's meetup, "Fail- Proofing Hadoop Clusters with Automatic Service Failover," at 345 Hudson St, 5th Floor, PulsePoint.
Our building recently changed its policy on event / guest registration and a last minute attempt to secure a new venue hasn't worked out. We've reset all RSVPs and opened registration with a new 70-person maximum and a cutoff of 3pm. If you would to attend tonight's meetup, you *must* change your RSVP to attending before 3pm. Check-in will also be strict, so no guests, and if your meetup name does not contain your full name or otherwise doesn't match what's printed on the identification you'll be showing, please let me know. Anyone whose name is not on the registration will not be permitted entrance.
We're very sorry and we'll be looking for alternative venues in the future. Especially given these circumstances, we are going to try to record the meetup if possible and will share it.
