Hi @dfossouo, at first, thank you for your answer and your informations. No, it doesn't work. We had several open cases at Hortonworks but nobody found a solution for it. We also have this problem with YARN UI and Zeppelin UI. I tried to add the missing files in the rewrite.xml but it's still the same issue. Thanks & Regards, Andreas ... View more

I did the curl command from 2.) from one of the cluster nodes (internal). I tested it now from my client pc with the following command: C:\01_Data\curl\src>curl curl -i -k -su <my_user> -X GET "https://<our_knox_host>:8443/gateway/default/static/bootstrap-3.0.2/js/bootstrap.min.js" Enter host password for user '<my_user>': HTTP/1.1 404 Not Found Date: Fri, 17 Feb 2017 07:01:45 GMT Set-Cookie: JSESSIONID=174cdd7p72bdupmc98his5fcr;Path=/gateway/default;Secure;HttpOnly Set-Cookie: rememberMe=deleteMe; Path=/gateway/default; Max-Age=0; Expires=Thu, 16-Feb-2017 07:01:46 GMT Content-Type: text/html; charset=ISO-8859-1 Cache-Control: must-revalidate,no-cache,no-store Content-Length: 342 Server: Jetty(9.2.15.v20160210) <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/> <title>Error 404 Not Found</title> </head> <body><h2>HTTP ERROR 404</h2> <p>Problem accessing /gateway/default/static/bootstrap-3.0.2/js/bootstrap.min.js.

Hi @Alexandru Anghel, at first, thank you very much for your help!! We have a hardware firewall with DMZ enabled in our cluster. It blocks all ports except 8443 for knox. Do you think this might be a problem? I checked your troubleshooting steps: 1.) Yes, the hostnames and ports are correctly resolved in default.xml 2.) curl on the namenode is working fine curl -i http://our_namenode_host:50070/static/bootstrap-3.0.2/js/bootstrap.min.js HTTP/1.1 200 OK X-FRAME-OPTIONS: SAMEORIGIN Accept-Ranges: bytes Content-Type: application/x-javascript Content-Length: 27748 Last-Modified: Tue, 29 Nov 2016 20:33:00 GMT Server: Jetty(6.1.26.hwx) 3.)

Thanks for your fast answer. I already tried it with a / at the end, I know this is a known bug in Oozie UI mapping.. I also replaced the service.xml and rewrite.xml with both github .xml's. After a Knox restart, the problems are still the same... My URLs: https://<our-knox-host>:8443/gateway/default/yarn/ https://<our-knox-host>:8443/gateway/default/hdfs/ Example call for Oozie (it's working without any problems): https://<our-knox-host>:8443/gateway/default/oozie/ ...

Knox UI Mapping Problem - ResourceManager Web UI

I would like to map the ResourceManager Web UI with Knox. I've set up the topology like: <service> <role>YARNUI</role> <url>http://{{rm_host}}:8088/</url> </service> <service> <role>HDFSUI</role> <url>http://{{namenode_host}}:50070/</url> </service> But the browser can't load the .css and .javascript from RM UI. "This page will not function without javascript enabled. Please enable javascript on your browser." I'm using Google Chrome but there are the same problems with Internet Explorer. JavaScript is working and RM UI directly is working as well. Developer Tool from Chrome: Failed to load resource: the server responded with a status of 404 (Not Found) Same Problems with NameNode UI. Can somebody help me please, or are there known problems? Thanks, Andreas ... View more

Is it possible to install Hue on a separate Node (VM), which is not a part of the HDP Cluster? I just need to configure hue.ini with the right Server Adresses and Ports from the cluster right? ... View more
