Todd Lipcon created YARN-2490: --------------------------------- Summary: Bad links to jobhistory server Key: YARN-2490 URL: https://issues.apache.org/jira/browse/YARN-2490 Project: Hadoop YARN Issue Type: Bug Reporter: Todd Lipcon
If you run an MR/YARN cluster without configuring the jobhistory URL, you get some really bad usability: - your jobs still produce JobHistory links - the job history link goes to whichever NM the AM happened to run on Even if you run the job history server on the same server as the RM, your links will be incorrect unless you've explicitly configured its hostname. If JobHistory isn't running, we shouldn't produce URLs (or we should by default embed JobHistory inside the RM). If we require a hostname beyond 0.0.0.0, we should refuse to start the JH server with 0.0.0.0 as its configuration. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
