Description Yurii Prokulevych 2016-03-08 07:12:07 UTC
Description of problem (clone of upstream bug):
===============================================
While having 2 instances of aodh-evaluator strange behavior is observed in logs:
- some alarms might be skipped by both evaluators
- some alarms might be evaluated by both evaluators
- all alarms are skipped by both evaluaotors

Coordination backend - redis.
Both evaluator are working as expected when just one instance is running.
Both running on different nodes.
