anyone could help me ? recently I found spark can't renew kerberos ticket,the error message like the follow picture,when I start my application,my program can run successfully,but it will crash almost after 24 hours.
I google it .the mostly anwser are that I don't renew the ticket tgt of principal.but i login when my program start up.next is my kerberos login code picture,and I am sure the principal and the keytab file is correct.
and i run a thread In the background to relogin the kerberos for renewing the ticket,but after 24 hours the application will still crash.next is my background thread timer picture, it will timed relogin .
