> 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
