Gilad, I have a simple UDF to convert date running successfully with Zeppelin 0.6.0 & Spark 1.6.1
###### UDF import org.apache.spark.sql.functions._ import org.apache.spark.sql.types._ import java.text.SimpleDateFormat val toDate = udf((t: String) =>{ val sdf = new SimpleDateFormat("MM/dd/yy HH:mm").parse(t) new java.sql.Date(sdf.getTime()) }) #### Later in another note val df3 = df.withColumn("DateTimeOpened2", toDate('DateTimeOpened)) Looking at your exception there is CNF, perhaps related to a generated class. Can you please try with 0.6.0?
