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. -- Sincerely, Darshan
