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
