Siddharth Seth commented on HIVE-10394:
---------------------------------------

The information isn't actually being sent across to the AM. What's handled 
right now is a response to the submitWork request. However, once a request 
moves onto the scheduler queue for execution at a later point - an RPC 
invocaiton will be required to inform the AM about the status of the task. This 
would be an addition to LlapTaskUmbilicalProtocol.

> LLAP: Notify AM of pre-emption
