Class BreakableService

java.lang.Object
  org.apache.hive.service.AbstractService
      org.apache.hive.service.BreakableService

All Implemented Interfaces:

Service

public class BreakableService
extends AbstractService

This is a service that can be configured to break on any of the lifecycle events, so test the failure handling of other parts of the service infrastructure. It retains a counter to the number of times each entry point is called - these counters are incremented before the exceptions are raised and before the superclass state methods are invoked.
