apache zeppelin in shinyproxy

Hi everyone,

I’ve been trying to run the apache zeppelin example from here on my local machine: https://github.com/openanalytics/useR-2019-docker-for-data-science/tree/master/shinyproxy-docker-compose

I’ve encountered two problems that I have not been able to solve, possibly for lack of knowledge how to configure shinyproxy or spring.

problem 1: using the template simple authentication of zeppelin in the shiro.ini file I get an error from spring boot’s StrictHttpFirewall, preventing the zeppelin docker from running at all since it tries to pass a jsessionid in the url ( ;JSESSIONID=.... ) which is regarded as not secure from spring. I’ve tried several ways of trying to force cookie useage (which supposedly fixes this), but havent been able to get it work.
I saw that spring’s api has a function to allow semicolons (https://docs.spring.io/spring-security/site/docs/4.2.12.RELEASE/apidocs/org/springframework/security/web/firewall/StrictHttpFirewall.html#setAllowSemicolon-boolean-) but I’m not sure how to set this in the shinyproxy config without modifying shinyproxy code itself.

Regardless of this first problem I’d also run into problem 2:
To get here I deleted shiro.ini to remove authentication from zeppelin.
The zeppelin header loads (with menu buttons etc), however when it tries to load a notebook, home.html, or any other file from its own zeppelin docker container, the springframework seems to catch the request and redirect it to within the shinyproxy docker container where those files dont exist:

shinyproxy_1  | 2019-08-20 15:00:11.407 ERROR 1 --- [  XNIO-2 task-8] io.undertow.request                      : UT005023: Exception handling request to /app_direct/zeppelin_notebook/app/home/home.html
shinyproxy_1  | 
shinyproxy_1  | org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.IllegalArgumentException: Unknown proxy spec: home

This happens for several files, also when trying to click any of the menu items. I’ve omitted the full stacktrace, but I can post it if needed.

Other shiny or dash applications (the sample ones) run just fine.

Mac OS X 10.14.3, Docker Desktop for mac, shinyproxy 2.3.0

Thanks for any help for this!

I can answer about your problem 2: indeed there was an issue in shinyproxy with running zeppelin notebooks, and the fix is already there in the development version, but hasn’t made it to a release yet…

Since you are already using docker-compose, the easiest way is to use openanalytics/shinyproxy-snapshot as your shinyproxy image which contains this fix (and it is actually used in the linked github example)

I can confirm that the 2.3.1 snapshot version of shiny does indeed fix this, thanks a lot!
For anyone else looking for this problem, you can find the snapshot .jar here (if it’s not in the official release yet): https://nexus.openanalytics.eu/nexus/content/repositories/snapshots/eu/openanalytics/shinyproxy/2.3.1-SNAPSHOT/
