Jason Dere commented on HIVE-16926:
-----------------------------------

Maybe I can just replace pendingClients/registeredClients with a single list 
and the RequestInfo can keep a state to show if the request is 
pending/running/etc.
Correct, the shared umbilical server will not be shut down. Is there any action 
needed on this part? I don't think anything is exposed to shut it down.

> LlapTaskUmbilicalExternalClient should not start new umbilical server for 
> every fragment request

> LlapTaskUmbilicalExternalClient currently creates a new umbilical server for 
> every fragment request, but this is not necessary and the umbilical can be 
> shared.
