سؤال
Is there a column store similar to Vertica that is built on top of Hadoop.. I am not talking about HBase as it is sparse matrix store and can not get the level of compression that can be achieved by something like Vertica?
Thanks

Are you looking for something like RCFile? It is a file type that uses a columnar store internally.

I haven't worked with Hadoop, but I know Vertica has been trying to integrate with Hadoop.

Look on Hadapt http://hadapt.com/
This is a commercial version of HadoopDB http://db.cs.yale.edu/hadoopdb/hadoopdb.html developed at Yale University. It can work with a column-oriented DB (which is installed on every node of a computer cluster) while leverages Hadoop for fault-tolerant execution.
