I would strongly encourage you to read the docs at, they are very useful in getting up and running:
https://github.com/datastax/spark-cassandra-connector/blob/master/doc/0_quick_start.md For your use case shown above, you will need to ensure that you include the appropriate version of the spark-cassandra-connectore assembly jar when you submit the job. The version you use should correspond to the version of Spark you are running. In addition, you will want to ensure that you set the "spark.cassandra.connection.host" as shown below, prior to creating the SparkContext. val conf = new SparkConf(true) .set("spark.cassandra.connection.host", "127.0.0.1") HTH -Todd On Fri, Jul 10, 2015 at 5:24 AM, Prateek . <prat...@aricent.com> wrote: > Hi, > > > > I am beginner to spark , I want save the word and its count to cassandra > keyspace, I wrote the following code > > > > import org.apache.spark.SparkContext > > import org.apache.spark.SparkContext._ > > import org.apache.spark.SparkConf > > import com.datastax.spark.connector._ > > > > object SparkWordCount { > > def main(args: Array[String]) { > > val sc = new SparkContext(new SparkConf().setAppName("Spark Count")) > > val tokenized = sc.textFile(args(0)).flatMap(_.split(" ")) > > val wordCounts = tokenized.map((_, 1)).reduceByKey(_ + _) > > wordCounts.saveToCassandra("sparkdata", "words", SomeColumns("word", > "count")); > > > > } > > and did spark-submit.
