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:
