Subject [jira] [Updated] (YARN-2571) RM to support YARN registry
Date Mon, 13 Oct 2014 21:50:34 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-2571-003.patch

patch -003 (against branch-2). Exceptions thrown in the async future actions are logged @
warn level before being rethrown. As the RM doesn't issue {{future.get()}} calls those exceptions
do not propagate to the RM (i.e. registry problems do not stop the RM working, simply registry
setup/teardown). The logging ensures that these problems are logged.

> 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
