> We currently run kinit command in a thread to renew kerberos credentials periodically. 
> {code:java}
>             Shell.execCommand(cmd, "-R");
>             if (LOG.isDebugEnabled()) {
>               LOG.debug("renewed ticket");
>             }
> {code}
> It seems useful to log the output of the kinit too.
