Interface Service

All Known Implementing Classes:

FlumeService, HBaseService, HdfsService, HiveService, ZookeeperService

public interface Service

Interface for MiniCluster Service implementations. Service implementation are generally constructed by the MiniCluster class. For this to be possible, implementations are expected to have a default constructor, and can automatically register themselves with the MiniCluster factory by having the static initializer:

 
 static {
   MiniCluster.registerService(MyService.class);
 }
