Datastax DSE 5.0 ( DSE analytics )
Description
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.
