Artem, You may need to restart few services.
[From the doc:] Re-start the Ganglia, Nagios, and MapReduce services. In Ambari Web. 1. Go to the Services View and select each service. 2. 3. Use the Management Header to stop and re-start each service. Thanks Sumit From: Artem Ervits <[email protected]> Reply-To: <[email protected]> Date: Friday, June 7, 2013 9:39 AM To: "[email protected]" <[email protected]> Subject: problems with upgrade to 1.2.3.7 Hello all, I just upgrade my server and agents to 1.2.3.7 and I noticed that all UI links are missing. For example: ganglia Web UI says ³:/ganglia² instead of ³servername/ganglia² and jobtracker says ³:50030² instead of ³servername:50030². Ganglia metrics also shows 404 error Not found where metrics would show. Any idea?
