[jira] [Updated] (YARN-4629) Distributed shell breaks under strong security

     [ https://issues.apache.org/jira/browse/YARN-4629?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Daniel Templeton updated YARN-4629:
-----------------------------------
    Attachment: YARN-4629.001.patch

In this patch, the potential exception from {{InetAddress.getLocalhost()}} is uncaught because if it's thrown, the right response is for the client to fail.

> If the auth_to_local is set to map requests from unknown hosts to nobody, the dist shell app fails.  The reason is that the client doesn't translate the _HOST placeholder to the local hostname.
