#1 is thrown from user code.

We use hadoop 2.7 which uses gauva 11.2 but our application uses 18.0. I think the hadoop's gauva is getting picked up instead of ours

Hi Janardhan,

#1 Is the exception thrown from your user code, or from Flink?

#2 is most likely caused due to a compiler / runtime version mismatch: http://stackoverflow.com/questions/10382929/how-to-fix-java-lang-unsupportedclassversionerror-unsupported-major-minor-versi

You compiled the code with Java8, but you try to run it with an older JVM.

Hi,

We are getting the following error on submitting the flink jobs to the cluster.

1. Caused by: java.lang.NoSuchMethodError: com.google.common.io.Resources.asCharSource

2. This is for entirely different job

Caused by: java.lang.UnsupportedClassVersionError: com/olacabs/fabric/common/Metadata : Unsupported major.minor version 52.0

But when we are running the flink locally, there is no error in both the jobs.
