Making Hadoop Safe for Mission Critical Applications

We all know there’s lots of excitement and buzz surrounding Hadoop, but talk to some CIOs in “non-web” industries about moving mission critical apps to the open source Big Data framework and you’re bound to hear a little fear in their voices.

They’re worried that Hadoop is not ready for primetime because it has a single point of failure. That is, if the NameNode in a cluster goes down, the entire cluster goes down. Spinning clusters back up into working order following a NameNode failure takes time and, by definition, mission critical applications can’t go down … ever. Until the SPOF is solved, more than a handful of Fortune 500 companies will continue paying Oracle through the nose rather than risk a disruption to critical apps.
