---------------------------------
Affects Version/s: 1.5.4

> Services failing to renew Kerberos ticket
> -----------------------------------------
>
> Key: ACCUMULO-4069
> URL: https://issues.apache.org/jira/browse/ACCUMULO-4069
> Project: Accumulo
> Issue Type: Bug
> Components: gc, master, monitor, tserver
> Affects Versions: 1.5.4, 1.6.4, 1.7.0
> Reporter: Josh Elser
> Assignee: Josh Elser
> Priority: Blocker
> Labels: kerberos
> Fix For: 1.6.5, 1.7.1, 1.8.0
>
>
> Got a report from a user that Accumulo services were dying after a period of
> time that was suspiciously similar to the Kerberos ticket lifetime.
> A Kerberos ticket lifetime is the amount of time that the ticket is valid
> (obtained from password or keytab). There is also a renewable lifetime
> associate with each ticket. Within the renewable lifetime duration, clients
> can "renew" their ticket for another "ticket lifetime" duration. For each, a
> lifetime of one day and a renewable lifetime of seven days: a ticket is valid
> for one day, but clients can renew that ticket up to 6 days after the
> original ticket expires.
> I do recall seeing a line of code in our services that has a comment saying
> it should spawn a thread specifically for this purpose, but I don't ever
> recall seeing that thread in thread dumps. My hunch is that the thread just
> isn't getting launched and we're not doing renewals
