------------------------------------

             Summary: Spark driver OOM cause Connection refused error in frontend
                 Key: ZEPPELIN-4662
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-4662
             Project: Zeppelin
          Issue Type: Bug
    Affects Versions: 0.9.0
            Reporter: Jeff Zhang


It is fine and normal for spark driver OOM, but displaying connection refused error is confusing for users.

We'd better to display more meaningful error like the yarn diagnostics info
{code:java}
