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?

Subject: Using UserGroupInformation in multithread process

I am using UserGroupInformation to get the Kerberos tokens.
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?
