Subject [jira] [Commented] (YARN-896) Roll up for long lived YARN
Date Fri, 19 Jul 2013 14:16:48 GMT

    [ https://issues.apache.org/jira/browse/YARN-896?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13713692#comment-13713692
] 

Robert Joseph Evans commented on YARN-896:
------------------------------------------

[~thw] I am not totally sure what you mean by app specific tokens.  Is this tokens that the
app is going to use to connect to other services like HBase? or is it something else?

[~eric14] and [~enis] Rolling upgrades is a very interesting use case.  We can definitely
add in a ticket to support this type of thing.  I agree that it needs to be thought through
some, and is going to require help from both the AM and YARN to do it properly.
