Use of nscala-time within spark-shell

[Hammam CHAMSI]

Hi All,


Thanks in advance for your help. I have timestamp which I need 
to convert to datetime using scala. A folder contains the three needed 
jar files: "joda-convert-1.5.jar  joda-time-2.4.jar 
 nscala-time_2.11-1.8.0.jar"

Using scala REPL and adding the jars: scala -classpath "*.jar"

I can use nscala-time like following:


scala> import com.github.nscala_time.time.Imports._

import com.github.nscala_time.time.Imports._


scala> import org.joda._

import org.joda._


scala> DateTime.now

res0: org.joda.time.DateTime = 2015-02-12T15:51:46.928+01:00


But when i try to use spark-shell:

ADD_JARS=/home/scala_test_class/nscala-time_2.11-1.8.0.jar,/home/scala_test_class/joda-time-2.4.jar,/home/scala_test_class/joda-convert-1.5.jar
 /usr/local/spark/bin/spark-shell --master local --driver-memory 2g 
--executor-memory 2g --executor-cores 1


It successfully imports the jars:


scala> import com.github.nscala_time.time.Imports._

import com.github.nscala_time.time.Imports._


scala> import org.joda._

import org.joda._


but fails using them

scala> DateTime.now

java.lang.NoSuchMethodError:
