Hi experts! I am trying to use spark in my restful webservices.I am using
scala lift frramework for writing web services. Here is my boot class
class Boot extends Bootable {
def boot {
Constants.loadConfiguration
val sc=new SparkContext(new
SparkConf().setMaster("local").setAppName("services"))
// Binding Service as a Restful API
LiftRules.statelessDispatchTable.append(RestfulService);
// resolve the trailing slash issue
LiftRules.statelessRewrite.prepend({
case RewriteRequest(ParsePath(path, _, _, true), _, _) if path.last ==
"index" => RewriteResponse(path.init)
})
}
}
When i remove this line val sc=new SparkContext(new
SparkConf().setMaster("local").setAppName("services"))
then it works fine.
I am starting services using command
java -jar start.jar jetty.port=1111
and get following exception
ERROR net.liftweb.http.provider.HTTPProvider - Failed to Boot! Your
application may not run properly
java.lang.NoClassDefFoundError:

Any suggestion please?
