spark streaming with sbt + cassandra connector dependency issue - scala

Question

Folks,
I am trying to integrated cassandra with spark streaming. Below is the sbt file:
scalaVersion := "2.11.8"
libraryDependencies ++= Seq(
"org.apache.spark" %% "spark-core" % "2.0.0" % "provided",
"org.apache.spark" %% "spark-streaming" % "2.0.0" % "provided",
"org.apache.spark" %% "spark-sql" % "1.6.1",
"com.datastax.spark" %% "spark-cassandra-connector" % "1.6.2",
"com.datastax.cassandra" % "cassandra-driver-core" % "3.0.0",
("org.apache.spark" %% "spark-streaming-kafka" % "1.6.0").
exclude("org.spark-project.spark", "unused")
)
I added below line(error line mentioned below) for cassandra integration:
val lines = KafkaUtils.createDirectStream[
String, String, StringDecoder, StringDecoder](
ssc, kafkaParams, topics)
//Getting errors once I add below line in program
lines.saveToCassandra("test", "test", SomeColumns("key", "value"))
lines.print()
Once I add above line, I see below error in IDE:
I see similar error if i try to package this project from command prompt:
FYR, I am using below versions:
scala - 2.11
kafka - kafka_2.11-0.8.2.1
java - 8
cassandra - datastax-community-64bit_2.2.8
Please help to resolve the issue.

As expected, it was dependency issue which is resolved by updating sbt file as below:
scalaVersion := "2.11.8"
libraryDependencies ++= Seq(
"org.apache.spark" %% "spark-core" % "2.0.0" % "provided",
"org.apache.spark" %% "spark-streaming" % "2.0.0" % "provided",
"org.apache.spark" %% "spark-sql" % "2.0.0",
"com.datastax.spark" %% "spark-cassandra-connector" % "2.0.0-RC1",
"com.datastax.cassandra" % "cassandra-driver-core" % "3.0.0",
("org.apache.spark" %% "spark-streaming-kafka" % "1.6.0").
exclude("org.spark-project.spark", "unused")
)
