Re: Passing application configuring to Flink uber jar


Hi Krishna,

I think the problem is that you are trying to pass in dynamic properties (-Dconfig.file=dev.conf) to an already started the cluster. The Flink cluster components or their JVMs need to know the env.java.opts at cluster start up time and not when the Flink job is submitted. You can check this by looking into the logs. They contain the parameters with which the JVMs are started.

You could, however, use the per job mode where you start a cluster per job (-m yarn-cluster).

Cheers,
Till

Hello All,

I have a Flink application that inherits configuration from application.conf in the resources folder. 

Now, I want to run this application on a cluster. I begin creating an fat jar "mvn clean assembly". 

This jar file is executed by executing the following command below
$FLINK_HOME/bin/flink run --class "com.test...." -D "env.java.opts=-Dconfig.file=dev.conf" /opt/resources/iot-flink-assembly-0.1.0.jar

This causes and error that the configuration key was not found. I could someone please let me know how to pass custom application.conf environment file to cluster. I could not find a lot of information online on how to do this.

Regards,
Krishna
