---------------------------------------------
Summary: Interpreter hangs in "downloading dependecies" when
Zeppelin is behind proxy
Key: ZEPPELIN-3998
URL: https://issues.apache.org/jira/browse/ZEPPELIN-3998
Project: Zeppelin
Issue Type: Bug
Affects Versions: 0.8.1, 0.8.0
Reporter: Fabiano Francesconi
I am running Zeppelin behind a proxy (meaning that there is no Internet
connectivity in the data center). However, locally I have a repository
deployment that could serve artifacts to the various interpreters.
I have added my repository to the repositories section and everything works
flawlessly in other environments where internet access is granted. In this
specific environment, each interpreter has a spinning circle "dependencies are
downloaded" which prevents users from using it. As a note, after few hours
typically everything goes back to green, as I assume the connection times out
and the work can proceed.
By looking to the connections, I see a connection open towards
`151.101.36.209:80` (I assume is repo.maven) with a fixed SYN_SENT status. This
tells me that the problem is not about reaching my repositories but rather to
access the central one, which I cannot delete nor disable.
I tried to do everything I could:
* Exported http_proxy and https_proxy env variables
* Passed "http/s.proxyHost" system properties to the JVM
Nothing seems to work. Are there any known workarounds to the problem?
