Subject [jira] [Commented] (YARN-4629) Distributed shell breaks under strong security
Date Fri, 22 Jan 2016 22:38:39 GMT

    [ https://issues.apache.org/jira/browse/YARN-4629?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15113259#comment-15113259
] 

Daniel Templeton commented on YARN-4629:
----------------------------------------

Right problem, wrong solution.  The client should be replacing the _HOST string with the RM's
hostname, which is what MR does.

> 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.
