Subject [jira] [Commented] (YARN-679) add an entry point that can start any Yarn service
Date Sat, 22 Apr 2017 11:41:04 GMT

    [ https://issues.apache.org/jira/browse/YARN-679?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15979865#comment-15979865

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

javac warnings are all about use of Signal in IrqHandler. This is to be expected. By moving
signal setup into one file, we can move other uses in the code to it, so providing one place
for the complaints and making things set up in case Oracle do ever change the API

> 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 interrupt.
> Provide one that takes any classname, and a list of config files/options
