File be/src/runtime/query-state.cc:

PS6, Line 199:     // If this fragment instance is not prepared, it must be 
reporting an error.
             :     DCHECK(fis->IsPrepared() || !status.ok());
> The race might exist. I'm looking at the code to check.
If fis==null case doesn't report the error, then that's a bug we need to fix 
since we need to report errors that can occur before we have instances (e.g. 
the call from StartFInstances() to ReportExecStatusAux()).


PS6, Line 328: prepare_status
> The idea is to share the codepath below, which is waiting for the fragment 
hmm, okay. the flow of all this is pretty complicated but I suppose we'll be 
reworking this entirely pretty soon anyway.
