Date Thu, 05 Sep 2013 10:55:52 GMT

    [ https://issues.apache.org/jira/browse/YARN-1143?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13758978#comment-13758978

Steve Loughran commented on YARN-1143:

thinking about this some more, I'd like the names to match that of valid hostnames. Why? it'd
let us implement a service registry that offered a DNS interface

>                 Key: YARN-1143
>                 URL: https://issues.apache.org/jira/browse/YARN-1143
>             Project: Hadoop YARN
>          Issue Type: Improvement
>    Affects Versions: 2.1.0-beta
>            Reporter: Steve Loughran
>            Priority: Minor
> YARN-1001 is an example of a RESTy API to the RM's list of apps and app types -and it
shows that we may want to add some restrictions on the characters allowed in an app name or
type (or at least forbid some) -before it is too late.
> If we don't do that, then tests should verify that you can have apps with high-unicode
names as well as other troublesome characters
