[jira] [Commented] (SAMZA-727) Support for Kerberos

["Chen Song (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SAMZA-727?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15223626#comment-15223626 ] 

Chen Song commented on SAMZA-727:
---------------------------------

If I understand that correctly, I think the launch context that cannot be updated is the launch context for AM but not for containers.

* AM will re-login from the keytab periodically and create new delegation tokens.
* Each time a container is requested or restarted, AM will always use the latest tokens to create the corresponding new launch context for the containers.
