Do you mean TGT tickets or tokens? Anyway, they should be across threads. Did you check if you're using the same UGI object in different threads?

I have a process in a Yarn container that is spawning another thread (slave). I am renewing the Kerberos Tokens in master thread but the slave thread is still using older Tokens. Are tokens not shared across threads in same JVM? Thanks Gaurav
