The connector utilized the DataStax Java driver under the hood to move data between Apache Cassandra and Apache Spark. This should be co-located with Apache Cassandra and Apache Spark on both on the same node.The connector will gather data from Apache Cassandra and its known token range and page that into the Spark Executor. The Apache Cassandra and Apache Spark Connector works to move data back and forth from Apache Cassandra to Apache Spark to utilize the power for Apache Spark on the data. sbin/start-master.sh Information about the Apache Spark Connector INSERT INTO testing123 (id, name, city) VALUES (2, 'Toby', 'NYC') Įxport SPARK_HOME=”//spark-x.x.x-bin-hadoopx.x INSERT INTO testing123 (id, name, city) VALUES (1, 'Amanda', 'Bay Area') ĬREATE TABLE IF NOT EXISTS testing123 (id int, name text, city text, PRIMARY KEY (id)) We will use this keyspace and table later to validate the connection between Apache Cassandra and Apache Spark. For more information about non default configurations review the the Apache Cassandra documentation. apache-cassandra-x.x.x/bin to your PATH but this is not required. apache-cassandra-x.x.x/bin/cassandra //This will start Cassandra Also, feel free to reach out and add comments on what worked for you! Hopefully, this works for you (as it did for me!), but if not use this as a guide.
DOWNLOAD SPARK PACKAGES INSTALL
Note: With any set of install instructions it will not work in all cases. Apache Cassandra - Apache Spark Connector.So you want to experiment with Apache Cassandra and Apache Spark to do some Machine Learning, awesome! But there is one downside, you need to create a cluster or ask to borrow someone else's to be able to do your experimentation… but what if I told you there is a way to install everything you need on one node, even on your laptop (if you are using Linux of Mac!).
