Subject [jira] [Updated] (MAPREDUCE-2762) [MR-279] - Cleanup staging dir after job completion
Date Mon, 17 Oct 2011 06:28:11 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-2762?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Mahadev konar updated MAPREDUCE-2762:

    Attachment: MAPREDUCE-2762.patch

Changed the patch to do cleanup after calling stop on all services in MRAppMaster.

- Added a job cleanup event which is synchronously called from the MRAppMaster Jobfinished

We could also add a job api for cleanupo but either of those are not very clean implementation.
The more I think, the earlier suggestion on sending events for de registering and then cleanup
is probably much cleaner.
