Subject [jira] [Updated] (YARN-2571) RM to support YARN registry
Date Mon, 03 Nov 2014 17:06:34 GMT

     [ https://issues.apache.org/jira/browse/YARN-2571?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Steve Loughran updated YARN-2571:
---------------------------------
    Attachment: YARN-2571-008.patch

Patch 008

fixes a bug noted by Jian He: the event handler for app attempts was invoking the AM container
cleanup and so prematurely deleting records tagged as persistent to app attempts.

This patch maps it to container completion events.

> The RM needs to (optionally) integrate with the YARN registry:
> # startup: create the /services and /users paths with system ACLs (yarn, hdfs principals)
> # app-launch: create the user directory /users/$username with the relevant permissions
(CRD) for them to create subnodes.
> # attempt, container, app completion: remove service records with the matching persistence
and ID
