Github user karuppayya commented on the issue: https://github.com/apache/zeppelin/pull/1663 Thanks @felixcheung . Looks like i read only part of the exception line and thought it was not due to this PR. I have fixed it now. The exception related to `websocket connected` tooltip still remains ` org.openqa.selenium.NoSuchElementException: Unable to locate element: {"method":"xpath","selector":"//i[@tooltip='WebSocket Connected']"} ` @Leemoonsoo
