Re: Measuring eventual consistency latency

Re: Deserialize Map[Int, UDT] to a case class from Spark Connector

Hi Guillermo Which version of Spark are you using? Starting with Version 2.0, Spark is built with Scala 2.11 by default. If you are using a prior version (which looks like it's the case since your error message mention scala 2.10), you might need to build it yourself from sources with Scala 2.11

Cassandra with Spark, select a few columns with case class

I'm trying to get a few columns from a Cassandra table from Spark and put them in a case class. If I want all the columns that I have in my case class works. But, I only want to bring a few of them and don't have a specific case class for each case. I tried to overload constructor in the case
