How to renew Kerberos ticket to run balancer for long time?

Hi, all
 
Recently I have set up Kerberos security for a Hadoop cluster and added a few data nodes to it.
 
While running hdfs balancer, I found that Kerberos ticket is expired and balancer stop.
The Kerberos ticket has 1day lifetime with 7days max renewable lifetime.
 
Are there any options to automatically renew the ticket while running balancer?
Or should I re-start it everyday?
 
Best wishes
