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?
> UGI should not try to renew non-renewable kerberos tickets

> Key: HADOOP-6976
> URL: https://issues.apache.org/jira/browse/HADOOP-6976
> Project: Hadoop Common
> Issue Type: Bug
> Components: security
> Affects Versions: 0.22.0
> Reporter: Todd Lipcon
>
> 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.
