## Class DistributedRunner

- java.lang.Object
- - org.apache.jmeter.engine.DistributedRunner

-     public class DistributedRunner
      extends Object

  This class serves all responsibility of starting and stopping distributed tests. It was refactored from JMeter and RemoteStart classes to unify retry behavior.
