This is a spike for integrating Spark + Apache Cassandra support into GeoTrellis.

Install Spark and launch a standalone master server using $SPARK_HOME/sbin/start-master.sh. This will print out the spark:://HOST:PORT URL used to connect workers.

Then, start a worker using ./bin/spark-class org.apache.spark.deploy.worker.Worker spark://IP:PORT. Check that it is connected at the master's portal, default http://localhost:8080/.

Install Cassandra and launch a local cluster using sudo service cassandra start. Check that it is running using nodetool status.

Note the version compatibility requirements between Spark, Cassandra, and Datastax's Connector.

After setting up your Spark and Cassandra clusters, edit Main.scala to point to your clusters. Run sbt run to execute the main function, which provides an example of interacting with RDDs in your Cassandra tables.
