Subject Class cast exception while using Data Frames
Date Mon, 26 Mar 2018 20:39:21 GMT
Hi guys,

I have a Map[(String, String), Double] as one of my columns. Using

input.getAs[Map[(String, String), Double]](0)

 throws exception: Caused by: java.lang.ClassCastException:
org.apache.spark.sql.catalyst.expressions.GenericRowWithSchema cannot
be cast to scala.Tuple2

Even the schema says that key is of type struct of (string, string).

Any idea why this is happening?
