Scheduler calls function in DCHECK, leading to crash

    Details

      Description

      The fix for IMPALA-4494 wrapped the call to backend_config_.LookUpBackendIp in simple-scheduler.cc:922 in a DCHECK, effectively disabling it in release builds. This leads to a crash when backend_ip is empty.

      921   IpAddr backend_ip;
      922   DCHECK(backend_config_.LookUpBackendIp(backend.address.hostname, &backend_ip));
      923   DCHECK(!backend_ip.empty());
      924   assignment_heap_.InsertOrUpdate(backend_ip, scan_range_length,
      925       GetBackendRank(backend_ip));
