Line 945: DCHECK(!exec_state->query_status().ok());
If we're upholding our claim in query-exec-state.h "We enforce the invariant 
that query_status_ is not OK iff query_state_ is EXCEPTION, given that lock_ is 
held.", then we should be able to also DCHECK the converse, i.e. if 
operation_state != error, then query_status() is OK, right?

File be/src/service/query-exec-state.h:

Line 109: UpdateQueryState
So now that I re-read this, I think it's misleading to keep the same name while 
this only can be used for non-error states. While "UpdateNonErrorQueryState()" 
sounds bad, I think we should better expose the behavior that this is only for 
Error states. I think someone adding code could easily use this function 
without thinking.
