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

             Summary: Don't print status stack trace when propagating thrift 
status in Coordinator::BackendState::Exec()
                 Key: IMPALA-6993
                 URL: https://issues.apache.org/jira/browse/IMPALA-6993
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
    Affects Versions: Impala 3.0
            Reporter: Dan Hecht
            Assignee: Dan Hecht


We should use Status::Expected() here, just like it's used above. The stack 
trace isn't interesting and the error is expected once we get down this path. 
(I'm not sure why we don't just use {{exec_status}} though, but presumably the 
prefix was added for a reason).
{code:java}
Status exec_status = Status(thrift_result.status);
if (!exec_status.ok()) {
  const string& err_msg = Substitute(ERR_TEMPLATE, PrintId(query_id_),
  exec_status.msg().GetFullMessageDetails());
  VLOG_QUERY << err_msg;
  status_ = Status(err_msg);
  return;
}
{code}
