If you want true integration of Cassandra and Hadoop and Spark then you will need to use Datastax Enterprise (DSE). There are connectors that will allow MapReduce over vanilla Cassandra, however, they are just making requests to Cassandra under the covers while DSE uses CFS which is similar to HDFS.

There are instructions on how to use Hadoop or Spark. However, it appears to me that according to these instructions, Hadoop and Spark just submit requests to Cassandra just like any other client would. So, I'm not sure what is meant by "integration". Any pointers? Thanks! Best, Oliver -- Oliver Ruebenacker Solutions Architect at Altisource Labs Be always grateful, but never satisfied.
