Jian He commented on YARN-800: ------------------------------ The link is not broken in local cluster because by default local cluster use localhost(0.0.0.0) as RM Ip Address. This problem occurs on real cluster where RM is using real IP address, and RM_WEBAPP_ADDRESS is still defaulting to '0.0.0.0', we should default RM_WEBAPP_ADDRESS to RM_ADDRESS. If we specify RM_WEBAPP_ADDRESS explicitly, this problem will not occur > Clicking on an AM link for a running app leads to a HTTP 500 > ------------------------------------------------------------ > > Key: YARN-800 > URL: https://issues.apache.org/jira/browse/YARN-800 > Project: Hadoop YARN > Issue Type: Bug > Affects Versions: 2.1.0-beta > Reporter: Arpit Gupta > Priority: Critical > > Clicking the AM link tries to open up a page with url like > http://hostname:8088/proxy/application_1370886527995_0645/ > and this leads to an HTTP 500 -- This message is automatically generated by JIRA.
