Last change on this file since 6178 was 6168, checked in by cneumuel, 13 years ago

#1233

  • removed Job-dto objects from slave core (since it stores outdated objects)
  • added command textbox to HiveJobView
  • improved the way the control buttons behave in HiveJobView
  • improved job control (pause and stop is also possible when job is not currently calculating)
  • improved gantt chart view (last state log entry is also displayed)
  • unified code for downloading jobs between experiment manager and hive engine
