java.lang.Object

org.apache.hadoop.hbase.StartMiniClusterOption

@InterfaceAudience.Public
public final class StartMiniClusterOption
extends Object

Options for starting up a mini cluster (including an hbase, dfs and zookeeper clusters) in test. The options include HDFS options to build mini dfs cluster, Zookeeper options to build mini zk cluster, and mostly HBase options to build mini hbase cluster. To create an object, use a StartMiniClusterOption.Builder. Example usage:

    StartMiniClusterOption option = StartMiniClusterOption.builder().
        .numMasters(3).rsClass(MyRegionServer.class).createWALDir(true).build();
 

Default values can be found in StartMiniClusterOption.Builder.
