Disconnected from Web App
Hello!
Beginner user here...
I'm running on CDH 5.3/Spark 1.2. I was able to access the web app,
but is says I am disconnected in the top right corner and I am unable
to create a note.
Details:
1) Didn't change env.sh as I am okay with running locally, do I still
need to set env variables?
2) Spark Interpreter blank fields:
spark.cores.max ; spark.home ; spark.yarn.jar (makes sense)
Thank you for the help/suggestions!
Best,
Su

Ahh got it, so once I tunneled into 8086 and 8087, I was able to
connect to the web app on 8086. Thank you!

okay I see, Zeppelin use 2 ports, one for the web and the other one for
websocket.
the websocket is bind to zeppelinweb + 1.
in your case, since you changed Zeppelin port from 8080 to 8086 the
websocket port will be 8087. you might add this one in your firewall rule.

So, 8080 and 8081 are open, but they are used by Spark. So I changed
the port to 8086 in the zeppelin-site.xml file. I am tunneling into
8086 and am able to see the web app at localhost:8086. However, when I
get to the web app, on the top right corner it says "Disconnected",
and when I try to create a new note, nothing happens. I've tried
attaching a screenshot, not sure if it will come through.
I can browse to the Interpreter, but that's about it.
Thanks for the help!

hi,
can you make sure that the port 8080 and 8081 are open? you may have to
open it from your firewall.
