Hi Moon, As said by you, I have checked the logs directory and came to know what the error is. Thanks moon, for the quick response.
Actual error is "when we are mentioning ZEPPELIN_OPTS variable with -Dhdpxxxxxxx value" in 'zeppelin-env.sh' file...we are getting error. But, when we commented it.....it was working fine. Thanks, Snehit ________________________________ From: moon soo Lee [m...@apache.org] Sent: 05 January 2016 05:07:36 To: users@zeppelin.incubator.apache.org Subject: Re: Zeppelin Connection Refused Error If restart does not work, could you check any error or exceptions in any file in logs directory ? that might help see the reason for the exception you see.

Could you restart the interpreter which is bound to notebook and try again? Hope it helps.
