Hi Felix, You need to also specify the path to your main class. For example: ./flink run -p10-v --class org.apache.flink.graph.example.MusicProfiles then jar and arguments
-p is the desired degree of parallelism and --class needs to be followed by the path I was talking about, Beast of luck :) Andra On Wed, Jun 10, 2015 at 10:24 PM, Felix Neutatz <neut...@googlemail.com> wrote: > Hi, > > I try to run this Scala program: > > https://github.com/FelixNeutatz/wikiTrends/blob/master/extraction/src/main/scala/io/sanfran/wikiTrends/extraction/flink/DownloadTopKPages.scala > on a cluster. > > I tried this command: > > /share/flink/flink-0.9-SNAPSHOT/bin/flink run > /home/neutatz/jars/extraction-1.0-SNAPSHOT.jar > io.sanfran.wikiTrends.extraction.flink.DownloadTopKPages > > org.apache.flink.client.program.ProgramInvocationException: Neither a > 'Main-Class', nor a 'program-class' entry was found in the jar file. > at > > org.apache.flink.client.program.PackagedProgram.getEntryPointClassNameFromJar(PackagedProgram.java:501) > at > > org.apache.flink.client.program.PackagedProgram.<init>(PackagedProgram.java:134) > at > > org.apache.flink.client.program.PackagedProgram.<init>(PackagedProgram.java:102) > at org.apache.flink.client.CliFrontend.buildProgram(CliFrontend.java:654) > at org.apache.flink.client.CliFrontend.run(CliFrontend.java:256) > at > org.apache.flink.client.CliFrontend.parseParameters(CliFrontend.java:880) > at org.apache.flink.client.CliFrontend.main(CliFrontend.java:922) > > Do I have to change my Scala program or can I use another command? > > Thank you for your help, > Felix >
