Hey, I have Flink code passing all its dependencies through
ExecutionEnvirnment object. I run my code remotely on cluster and it errors:
Exception in thread "main"
org.apache.flink.client.program.ProgramInvocationException: The program
execution failed: Job execution failed.

The main problem is that it can't find my class FlinkStreaming!!!! I run my
code using IDE. When I try running the code using a maven fat jar in
terminal, it worked correctly but using the IDE this error happens!
