Hi,
Did you check solutions from here - https://stackoverflow.com/questions/48904881/could-not-resolve-substitution-to-a-value-akka-stream-materializer-in-aws-la Regards, Georgi Stoyanov ________________________________ From: Sandybayev, Turar (CAI - Atlanta) <turar.sandyba...@coxautoinc.com> Sent: Thursday, May 31, 2018 11:23:22 PM To: user@flink.apache.org Subject: Looking for a working POM file example for EMR cluster Hi, I'm looking for a sample POM file that works when running on EMR cluster. I'm new to Flink and EMR, so I'm simply following AWS EMR documentation on Flink and I am creating a Step and submitting my program JAR file. My program is just a slight modification of the Wikipedia example. I was trying to follow an example from AWS reference architecture for their Taxi events example: https://github.com/aws-samples/flink-stream-processing-refarch/blob/master/flink-taxi-stream-processor/pom.xml However, I've been seeing various errors having to do with dependencies and ClassNotFoundExceptions for basic common Flink dependencies. I tried removing excludes from the maven-shade-plugin section of the POM file from the reference architecture, and now I'm seeing the following exception: Exception in thread "main" com.typesafe.config.ConfigException$UnresolvedSubstitution: Could not resolve substitution to a value: ${akka.stream.materializer} If I run a local Flink cluster and submit my JAR, I'm not seeing any issues with pretty much any way I modify the POM file. I would greatly appreciate if someone can point me to a working POM example. Thanks! Turar
