Subject [jira] [Commented] (YARN-575) ContainerManager APIs should be user accessible
Date Mon, 29 Apr 2013 22:22:16 GMT

    [ https://issues.apache.org/jira/browse/YARN-575?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13644964#comment-13644964

Siddharth Seth commented on YARN-575:

I'm fine going the route of getting container status from the RM - when required. Assuming
we keep the NM equivalent though, for AMs to use.
The AppTokens will be used for Authentication as well as Authorization for getContainerStatus
calls ?

>             Project: Hadoop YARN
>          Issue Type: Sub-task
>          Components: nodemanager
>    Affects Versions: 2.0.4-alpha

>            Priority: Critical
> Auth for ContainerManager is based on the containerId being accessed - since this is
what is used to launch containers (There's likely another jira somewhere to change this to
not be containerId based).
> What this also means is the API is effectively not usable with kerberos credentials.
> Also, it should be possible to use this API with some generic tokens (RMDelegation?),
instead of with Container specific tokens.
