-----------------------------------

             Summary: Carbondata with Datastax / Cassandra
                 Key: CARBONDATA-854
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-854
             Project: CarbonData
          Issue Type: Improvement
          Components: spark-integration
    Affects Versions: 1.1.0-incubating
         Environment: Datastax DSE 5.0 ( DSE analytics )
            Reporter: Sanoj MG
            Priority: Minor
             Fix For: 1.1.0-incubating


I am trying to get Carbondata working in a Datastax DSE 5.0 cluster. 

An exception is thrown while trying to create Carbondata table from spark shell. Below are
the steps: 

scala> import com.datastax.spark.connector._
scala> import org.apache.spark.sql.SaveMode
scala> import org.apache.spark.sql.CarbonContext
scala> import org.apache.spark.sql.types._

scala> val cc = new CarbonContext(sc, "cfs://127.0.0.1/opt/CarbonStore")

scala> val df = cc.read.parquet("file:///home/cassandra/testdata-30day/cassandra/zone.parquet")

scala> df.write.format("carbondata").option("tableName", "zone").option("compress", "true").option("TempCSV","false").mode(SaveMode.Overwrite).save()

Below exception is thrown and it fails to create carbondata table.
