> On SLES11, it was noticed that after 'ticket_lifetime', the kerberos ticket
> gets deleted by the Java krb5 library. [~mikesbrown] noticed this from 2.11,
> and we confirmed that it shows up in 2.12 as well.
> I turned on the Java kerberos debug logging and found this in the log
> messages:

> The backend ticket acquisition thread however keeps running and claiming to
> have re-acquired a ticket every 'ticket_lifetime' period.
> I tried turning off the 'use_kudu_kinit' flag and this bug didn't show up in
> that mode.
> Still investigating the bug.
