Zeppelin Home Page Blank

[#1]

Hi All,

I have setup Zeppelin through Ambari on AWS. I am able to get to the Ambari page on port 9995 from a windows machine on AWS. I then did a port forwarding setup so that anyone who accesses the IP on port 80 should be able to go Ambari.

I am able to get to the Zeppelin home page from my laptop after setting up the httpd conf but the page is coming blank. I also un-commented the below 3 lines in Ambari and re-started the Zeppelin service but still it is coming as blank

sessionManager = org.apache.shiro.web.session.mgt.DefaultWebSessionManager
securityManager.sessionManager = $sessionManager
# 86,400,000 milliseconds = 24 hour
securityManager.sessionManager.globalSessionTimeout = 86400000

I did a port forwarding as by default port 80 is opened through our VPC to connect to a web URL on AWS.

Any help in resolving would be greatly appreciated

I resolved it, by adding few extra lines in the rewrite rule to handle websocket interaction

RewriteRule ^/ws(.*)$ ws://localhost:9995/ws [P]
