Subject Re: Unable to find org.apache.spark.sql.catalyst.ScalaReflection class
Date Thu, 12 Mar 2015 19:10:41 GMT
BTW, I was running tests from SBT when I get the errors. One test turn a
Seq of case class to DataFrame.

I also tried run similar code in the console, but failed with same error.

I tested both Spark 1.3.0-rc2 and 1.2.1 with Scala 2.11.6 and 2.10.4

Any idea?
