Thanks everyone for the reply. Still having issues.
Moon, I had tried
sudo -u zeppelin /usr/lib/zeppelin/bin/zeppelin-daemon.sh restart
and it did not work.
I am using the Zeppelin Version 0.7.1. I checked the logs and in the
logs, I saw the error message that the port 8890 already in use. Since
sudo stop zeppelin did not work , I killed the process that wasusing 8890.
Now I am able to start and stop zeppelin using sudo start zeppelin and sudo
stop zeppelin.
But now I have a new problem, The cassandra interpreter works fine, but the
spark interpreter hangs, and I have to cancel the job. Even a simple job as
the following hangs
val df1 = sc.parallelize(1 to 10).toDF()
df1.show()
I see the following in the log
WARN [2017-06-05 03:33:33,283] ({Timer-0} Logging.scala[logWarning]:66) -
Initial job has not accepted any resources; check your cluster UI to ensure
that workers are registered and have sufficient resources
Please help, I just made some config changes and wanted to restart Zeppelin
and now I messed up my presentation.
