InferredSchema Example in Spark-SQL
Hi All, Was trying the Inferred Schema spart example http://spark.apache.org/docs/latest/sql-programming-guide.html#overview I am getting the following compilation error on the function toRD() value toRD is not a member of org.apache.spark.rdd.RDD[Person] [error] val people = sc.textFile(/home/ubuntu/work/spark-src/spark/examples/src/main/resources/people.txt).map(_.split(,)).map(p = Person(p(0), p(1).trim.toInt)).toRD() [error] Thanks Rajdeep
