Being currently involved in a Hadoop/HBase project for storing a mass of
sensor data, HBase is doing pretty fine on top of HDFS. HDFS is widely
used in huge installations (Google et al.) and AFAIK the problem with
the name node currently being a single-point-of failure, is going to be
sorted out.

Needless to say, that a lot of money is currently going into the "Big
Data Management" stuff. Will be interesting to see how NuoDB will merge
the two worlds: SQL and Scale-Out or in NuoDB terms "Elastically
Scalable", as HBase ensures row-level consistency only and no real
transaction support, no SQL language etc., but it scales very nicely
when you have sorted out how to design your row-key. And I like the
flexibel model to add qualifiers, aka fields in the relational world,
dynamically without the need to change the underlaying model.


Regards,
Thomas
