Configuring Zeppelin Spark Interpreters

[#1]

I installed zeppelin manually on my node(not sandbox) but after following through the instructions on configuring the spark notebook I notice that when I run "sc.version" it throws me an error(below):

sc.version

@Koffi Did you configure the interpreter correctly?

refer to this link for more details

@Yogeshprabhu thanks very much for reaching back to me, I redid the steps listed in the link above and still experiencing the same errors.I attached photos of my configs. Thanks alot

@Koffi

Can you also post a screenshot of your yarn interpreter settings on your zeppelin ?

[#5]

@Yogeshprabhu I attached spark-yarn-client interpreter settings. Thanks

[#6]

Try restarting spark interpreter within Zeppelin, if that doesn't work restart zeppelin. zappelin-daemon.sh restart can do the Zeppelin restart.

[#7]

@vshukla restarted the zeppelin interpreter and zappelin-daemon.sh still geting the same error. Thanks

[#8]

check out your local mac firewall settings, make sure nothing else is running on the same ports. make sure nothing requires root access. also restarting the server will sometimes do the trick.

[#9]

@Timothy Spann nothing is conflicting with firewall settings and there are no services running on port 9995 except zeppelin.Since server in use I'll restart at down-time

[#10]

is spark running in the cluster? is it on the default port.

can you access Spark? can you get to the spark history UI
