             Summary: KafkaWindowedWordCountExample fails with JobName invalid
                 Key: BEAM-126
                 URL: https://issues.apache.org/jira/browse/BEAM-126
             Project: Beam
          Issue Type: Bug
          Components: runner-flink
            Reporter: William McCarthy
            Assignee: Maximilian Michels


I get the following when I try to run the KafkaWindowedWordCountExample.

I'm able to fix it by changing line 106 of that file to:
    options.setJobName("kafkawindowword" + options.getWindowSize() + "seconds");


flink run -c org.apache.beam.runners.flink.examples.streaming.KafkaWindowedWordCountExample target/beam-1.0-SNAPSHOT.jar 
test cl-mdgy:2181 cl-pu4p:9092,cl-y06o:9093 mygroup
