Subject [jira] [Updated] (YARN-679) add an entry point that can start any Yarn service
Date Tue, 14 May 2013 00:07:16 GMT

     [ https://issues.apache.org/jira/browse/YARN-679?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Steve Loughran updated YARN-679:
--------------------------------

    Attachment: YARN-679-001.patch

This is to show Vinod why {{Service.waitForServiceToStop()}} is useful -an interrupt handler
hooked in to ^C calls give the service 30s grace before exiting

> 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
