Subject [jira] [Updated] (YARN-530) Define Service model strictly, implement AbstractService for robust subclassing, migrate yarn-common services
Date Sun, 02 Jun 2013 18:01:21 GMT

     [ https://issues.apache.org/jira/browse/YARN-530?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Steve Loughran updated YARN-530:
--------------------------------

    Attachment: YARN-530-014.patch

Pulled the {{ServiceShutdownHook}} code off to YARN-679, this eliminates two of the FindBugs
warnings. The remaining two are spurious as they note that an AtomicBool is being used for
both a wait/notify barrier as well as for the thread-safe get/set operations.
