Jason Lowe commented on YARN-6647:
----------------------------------
Thanks for the patch!
I agree with [~rohithsharma]'s comments. If the RMDelegationTokenSecretManager
receives an interrupted exception, either on the expired token remover thread
or on another thread, it should not cause the JVM to exit if it is being
shutdown. The other methods should be updated to handle interrupt exceptions
similarly even if they won't involve the expired token remover thread. The
state store itself could throw an interrupt exception, and the secret manager
should not tear down the JVM if it knows this interrupt exception is likely a
side effect of being shut down.
For the AsyncDispatcher change, the new wording is more confusing and doesn't
add much value. If the async dispatcher is seeing an InterruptedException then
the thread is being interrupted. The original wording conveys that
effectively. The new wording suggests a possible reason where the interrupt
was recognized, but the stack trace will show where the interrupt exception
originated. There are lots of methods besides queue put that will check for a
thread interrupted status and throw the exception, so I do not see a reason to
call out a specific one here especially when the exception stack trace will
show from whence it was thrown.
