Subject [jira] [Commented] (YARN-679) add an entry point that can start any Yarn service
Date Sat, 07 Jun 2014 09:42:02 GMT

    [ https://issues.apache.org/jira/browse/YARN-679?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14020769#comment-14020769
] 

Steve Loughran commented on YARN-679:
-------------------------------------

some of the compiler warning are about use of sun.misc for interrupt handling -that's all
in one class to avoid spreading complaints. We could actually move signal handlers to using
that wrapper for registry/callback, and reduce the number of warnings...

> There's no need to write separate .main classes for every Yarn service, given that the
startup mechanism should be identical: create, init, start, wait for stopped -with an interrupt
handler to trigger a clean shutdown on a control-c interrrupt.
> Provide one that takes any classname, and a list of config files/options
