> Present friendlier error for non-static main
> --------------------------------------------
>
> Key: MAPREDUCE-7251
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-7251
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Affects Versions: 2.9.2
> Reporter: Connor Taffe
> Priority: Minor
>
> When running a jar with hadoop jar, e.g. when submitting using gcloud dataproc jobs submit hadoop, a JAR with a non-static main gives a cryptic error message that could be clearer. The current error message in Hadoop 2.9.2 looks like:
> {code:java}
> Exception in thread "main" java.lang.NullPointerException
> at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
> at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)
> at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)
> at java.lang.reflect.Method.invoke(Method.java:498)
> at org.apache.hadoop.util.RunJar.run(RunJar.java:244)
> at org.apache.hadoop.util.RunJar.main(RunJar.java:158)
> at com.google.cloud.hadoop.services.agent.job.shim.HadoopRunJarShim.main(HadoopRunJarShim.java:12)
> {code}
> Instead, it would be more helpful to show an error message like "Method main must be static: foo.bar.BazMR".
