The Datastax connector is not part of the Apache Spark distribution, it's
maintained by Datastax directly. So please reach out to them for support.
Thanks!

> Key: SPARK-5887
> URL: https://issues.apache.org/jira/browse/SPARK-5887
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.2.1
> Environment: Spark 1.2.1
> Spark Cassandra Connector 1.2.0 Alpha2
> Reporter: Vijay Pawnarkar
>
> I am getting following class not found exception when using Spark 1.2.1 with
> spark-cassandra-connector_2.10-1.2.0-alpha2. When the job is submitted to
> Spark.. it successfully adds required connector JAR file to Worker's
> classpath. Corresponding log entries are also included in following
> description.
> From log statements and looking at spark 1.2.1 codebase it looks like the JAR
> get added to urlClassLoader via "Executor.scala's updateDependencies method".
> However when it time to execute the Task, its not able to resolve the class
> name.
