Well I was more thinking along the lines asking Grab not to download the servlet-api coming probably with Apache Spark.
But I did renamed the one in $GROOVY_HOME/lib and thibault's branch fixed my exception regarding Akka. I nevertheless have a new issue which again seems related to the way class are loaded. I really need to better understand which are the differences in running the very same script using the command line and GroovyShell ... there seems to be subtile differences that should explain that difference in behavior. Here is my new exception in case that rings a bell. tog GroovySpark $ $GROOVY_HOME/bin/groovy GroovySparkThroughGroovyShell.groovy org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in stage 0.0 failed 1 times, most recent failure: Lost task 0.0 in stage 0.0 (TID 0, localhost): java.lang.ClassNotFoundException: Script1$_run_closure1 at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:348) at org.apache.spark.serializer.JavaDeserializationStream$$anon$1.resolveClass(JavaSerializer.scala:67) Cheers Guillaume
