Zeppelin running in debug mode
Hi,
Can Zeppelin be run in debug mode so that I can remotely debug the code
through intelliJ? If so can someone help me out with the steps?

Hi Jonathan,
When I do that, and run a code in the notebook using any interpreter I get
the following error. But my IDE remote debugger has successfully connected
to the socket.

That should be possible, but how you do it might depend upon whether you
want to debug Zeppelin UI/server code or Zeppelin Spark interpreter code.
Then again, the same environment variable (ZEPPELIN_JAVA_OPTS is I think
what you want) might affect both anyway. What happens if you set
ZEPPELIN_JAVA_OPTS="-Xdebug
-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=1044" in
zeppelin-env.sh then restart the server?
BTW, all three of the messages you sent around this time were sent to my
Gmail spam folder with this message: "*Why is this message in Spam?* It has
a from address in wso2.com but has failed wso2.com's required tests for
authentication."
