I am currently using Spark 2.0.1 with Scala 2.11.8. However same code works
with Scala 2.10.6. Please advise if I am missing something
import org.apache.spark.sql.functions.udf
val getFileName = udf{z:String => z.takeRight(z.length
-z.lastIndexOf("/")-1)}
and this gives me following error messages
No Type Tag Available for String and
not enough arguments for method udf: (implicit evidence$2:
reflect.runtime.universe.TypeTag[String], implicit evidence$3:
reflect.runtime.universe.TypeTag[String])org.apache.spark.sql.expressions.UserDefinedFunction.
Unspecified value parameters evidence$2, evidence$3.
