Hi Igal: Thanks for pointing that out. I was able to add the dependency in and submit the job. For statefun-greeter example [1] I was able to submit the job to the cluster . But when I try out the statefun-data-stream example [2] I got the complaints saying that "There are no ingress defined" (I'm adding the full trace to the end of the email). (I'm also adding my pom to [3] and source file to [4].) From the example it appears the job uses the Datastream as ingress [5] so ideally the job should be able to receive events as trigger periodically (the job works fine with local environment). I also came across this issue [6] but I don't think it helps solving my problem. By any chance you'd know what's going on?
