[jira] [Created] (ZEPPELIN-2934) Get ConnectionException when using
ZeppelinHubRepo
Jeff Zhang created ZEPPELIN-2934:
------------------------------------
Summary: Get ConnectionException when using ZeppelinHubRepo
Key: ZEPPELIN-2934
URL: https://issues.apache.org/jira/browse/ZEPPELIN-2934
Project: Zeppelin
Issue Type: Improvement
Reporter: Jeff Zhang
When I configure zeppelin notebookrepo to use ZeppelinHubRepo, zeppelin server will take a long time to start up. It seems will sync up the data in zeppelin hub. And I can see many exception when it communicate with zeppelin hub, although finally zeppelin server can start properly.
