Spark Yarn mode - unsupported exception

Hello Users,

I am running into a spark issue "Unsupported major.minor version 52.0"

The code I am trying to run is
https://github.com/cpitman/spark-drools-example/


This code runs fine in spark local mode but fails horribly with the above
exception when you submit the job in the yarn mode.


spark-submit --class com.awesome.App --master yarn
./SparkDroolsExample-1.0-SNAPSHOT.jar


This happens on cloudera VM and a couple of real clusters as well.

I already tried to match and compile with the right JDKs etc.

I also tried switching the serializers for spark. No luck.


*Env Details *


Using Java JDK and JRE 1.8

Using Spark 1.6.0

Using Spark 2.1.0

Please let me know if I am totally missing something.

Darshan
