-----------------------------------------

Closing this issue as the agreement seems to be that it should be resolved on the client side.

> With the fix of IMPALA-4488, GetOperationStatus keeps the session alive so the client can wait for the running query finished before it fetches result. This works perfectly for *DBC clients, but unfortunately leads to issues for HUE. 
> Unlike other clients, HUE has a periodical status check for all queries opened in the UI to update the query status. This is hard-coded as 5 minutes, and any sessions opened by HUE won't be expired if the --idle_session_timeout is longer than 5 minutes, hence session expiration is not working properly for HUE. 
> I think GetOperationStatus should not reset session's last_accessed timestamp for finished or expired queries.
