frontend

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
