Hi Till,
many thanks for your effort. I finally got it working.
I'm a bit embarrassed because the issue was solved by using the same
flink-dist-JAR from the locally running Flink version. So to say I used
an older Snapshot version for compiling than for running :-[
Best Regards,
Philipp

Hi Philipp,
what I usually do to run a Flink program on a cluster from within my
IDE, I create a |RemoteExecutionEnvironment|. Since I have one UDF
(the map function which doubles the values) defined, I also need to
specify the jar containing this class. In my case, the jar is called
test-1.0-SNAPSHOT.jar.
|def main(args: Array[String]) {
// set up the execution environment
val env = ExecutionEnvironment.createRemoteEnvironment("localhost", 6123,
"target/test-1.0-SNAPSHOT.jar")
val elements = env.fromElements(1,2,3,4,5)
val doubled = elements.map(x => 2*x)
doubled.printOnTaskManager("TaskManager")
// execute program
env.execute("Flink Scala API Skeleton")
}

But I also tried your approach of how to submit jobs to Flink and it
worked for me as well. Therefore, I guess that there is something
wrong with your job. What happens in |PigStorage().load|?
Cheers,
Till

Hey Tim,
I think my previous mail was intercepted or something similar.
However you can find my reply below. I already tried a simpler job
which just does a env.fromElements... but still the same stack.
How do you normally submit jobs (jars) from within the code?
Best Regards,
Philipp

The code of the job is quite simple (just a test-case). As stated
before it works when using the wrapper script and the web client.
I think something is wrong in the submitJar method I posted
earlier. But here the code of the submitted job:
import org.apache.flink.api.scala._
import dbis.flink._
object load {
def tupleAToString(t: List[Any]): String = {
implicit def anyToSeq(a: Any) = a.asInstanceOf[Seq[Any]]
val sb = new StringBuilder
sb.append(t(0))
sb.toString
}
def main(args: Array[String]) {
val env = ExecutionEnvironment.getExecutionEnvironment
val A = PigStorage().load(env,
"/home/blaze/Documents/TU_Ilmenau/Masterthesis/projects/pigspark/src/it/resources/file.txt",
'\t')
A.map(t =>
tupleAToString(t)).writeAsText("/home/blaze/Documents/TU_Ilmenau/Masterthesis/projects/pigspark/result1.out")
env.execute("Starting Query")
}
}
Best Regards,
Philipp
