Yes, it is possible to use Apache Spark for accessing as well as analyzing data stored in Cassandra databases using the Spark Cassandra Connector. It needs to be added to the Spark project during which a Spark executor talks to a local Cassandra node and will query only local data.
Connecting Cassandra with Apache Spark allows making queries faster by means of reducing the usage of the network for sending data between Spark executors and Cassandra nodes.
