Subject [jira] Commented: (HADOOP-6976) UGI should not try to renew non-renewable kerberos tickets
Date Mon, 27 Sep 2010 18:49:33 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6976?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12915426#action_12915426
] 

Todd Lipcon commented on HADOOP-6976:
-------------------------------------

Any thoughts about whether we should issue a warning at login time if the user has a non-renewable
ticket? Maybe only if they have a non-renewable ticket which expires within the next hour
or two?

> When UserGroupInformation logs in a user from the ticket cache, it spawns a thread which
renews the TGT ticket before it expires (HADOOP-6656). This happens even for non-renewable
tickets, which results in error messages being printed to the console.
> We should only try to renew the ticket if it has the "Renewable" flag.
