Subject Re: Fail to cache rdd: java.lang.NoSuchMethodError: scala.Predef$.$conforms()Lscala/Predef$$less$colon$less;

Hi Denis,

This is really helpful. Yes, I need the original dataframe for other API.

Now I am using RDD[String, Row] as type and caching dataframe using:
val rdd = df.map(row => (row.getAs[String]("KEY"), row))

It works perfectly fine. Also I was able to reconstruct the dataframe using
values collection and schema of rdd.
