I’m using Spark 1.6.1
Class is case class DistinctValues(statType: Int, dataType: Int, _id: Int,
values: Array[(String, Long)], numOfMembers: Int,category: String)
and
error for newGnsDS.joinWith(newGnsDS, $"dataType”)
Exception in thread "main" org.apache.spark.sql.AnalysisException: cannot
r
Looks like you're using Spark 1.6.x
What error(s) did you get for the first two joins ?
Thanks
