Subject [jira] [Updated] (MAPREDUCE-2668) MR-279: APPLICATION_STOP is never sent to AuxServices
Date Tue, 11 Oct 2011 05:38:30 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-2668?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vinod Kumar Vavilapalli updated MAPREDUCE-2668:
-----------------------------------------------

    Status: Open  (was: Patch Available)

Patch mostly looks good. Some nit-picking:
 - ApplicationImpl.handleAppFinishWithContainersCleanedup() doesn't need the ApplicationID
argument.
 - AuxService.handle(): No need for the explicit check for Service.STATE.STARTED. We expect
the service to handle it similar to initApp().
 - TestAuxServices
    -- Please remove unused imports.
    -- Rename all_appIds to stoppedApps ?
    -- The messages for the assert should be the negations of what you already have.

Thanks.

> APPLICATION_STOP is never sent to the AuxServices only APPLICATION_INIT.  This means
that all map intermediate data will never be deleted.
