Should registration information of Kyuubi in ZK be cleaned up？

[merrily01]

Since I started testing the Kyuubi + Zookeeper method, it seems that the registration information of Kyuubi in ZK has never been cleaned up, and some of the services or engines have been disabled for a long time.
e.g.

Is this consistent with the design, or should there be any cleanup mechanisms necessary?

I can not recall my original design. :)

It should be deleted during the engine termination.

Thx，I think it should be deleted.

But in some scenarios, it may not seem as expected.

However, I haven't been able to determine which scenarios may have this issue. 😓

I think I can keep testing and following it.

thanks for taking care of it
