I am not sure why i am getting this error. Here is my code :-
val conf = new SparkConf(true).setAppName("TestRead")
conf.set(SPARK_CASS_CONN_HOST, config.cassHost)
conf.set("spark.cassandra.connection.timeout_ms","10000")
val sc = new SparkContext(conf)
sc.hadoopConfiguration.set("fs.s3a.impl", "org.apache.hadoop.fs.s3a.S3AFileSystem")
sc.hadoopConfiguration.set("fs.s3a.access.key", config.s3AccessKey)
sc.hadoopConfiguration.set("fs.s3a.secret.key", config.s3SecretKey)
val sqlContext = new SQLContext(sc)
val data = sqlContext.read.parquet(s"s3a://${config.s3bucket}/${config.s3folder}")
println(s"data size is ${data.count()}")
data.show()
if(config.cassWriteToTable){
println("Writing to Cassandra Table")
data.write.mode(SaveMode.Append).format("org.apache.spark.sql.cassandra").options(Map("table" -> config.cassTable, "keyspace" -> config.cassKeyspace)).save()
}
println("Stopping TestRead...")
sc.stop()
I have included the below dependencies in my build.sbt file:-
"org.apache.spark" % "spark-core_2.10" % "1.6.1" % "provided,test" ,
"org.apache.spark" % "spark-sql_2.10" % "1.6.1" % "provided",
"com.typesafe.play" % "play-json_2.10" % "2.4.6" excludeAll(ExclusionRule(organization = "com.fasterxml.jackson.core")),
"mysql" % "mysql-connector-java" % "5.1.39",
"com.amazonaws" % "aws-java-sdk-pom" % "1.11.7" exclude("commons-beanutils","commons-beanutils") exclude("commons-collections","commons-collections") excludeAll ExclusionRule(organization = "javax.servlet")
What could be the issue here ?
