Description

If one tries to launch, say, Native Scheduler just after Controller, most likely Native Scheduler fails with such the exception:

2017-07-11 08:55:46,932 (__init__.py:128) root ERROR> Uncaught exception
Traceback (most recent call last):
  File "/home/debian/klever/scheduler/bin/native-scheduler", line 37, in <module>
    scheduler_impl = native.Scheduler(conf, "scheduler/")
  File "/home/debian/klever/scheduler/bin/../schedulers/native.py", line 87, in __init__
    self.init_scheduler()
  File "/home/debian/klever/scheduler/bin/../schedulers/native.py", line 123, in init_scheduler
    self.update_nodes()
  File "/home/debian/klever/scheduler/bin/../schedulers/native.py", line 290, in update_nodes
    cacnel_jobs, cancel_tasks = self.__manager.update_system_status(self.__kv_url)
  File "/home/debian/klever/scheduler/bin/../schedulers/resource_scheduler.py", line 72, in update_system_status
    string = session.kv["states/" + node]
  File "/usr/local/lib/python3.4/dist-packages/consulate/api/kv.py", line 61, in __getitem__
    raise KeyError('Key not found ({0})'.format(item))
KeyError: 'Key not found (states/joker-klever-dev)'

This issue exists very long and always very complicated automatic deployments.
