Examples of org.apache.hadoop.hbase.ClusterId

org.apache.hadoop.hbase.ClusterId
The identifier for this cluster. It is serialized to the filesystem and up into zookeeper. This is a container for the id. Also knows how to serialize and deserialize the cluster id.


  public String getClusterId() {
    if (fileSystemManager == null) {
      return "";
    }
    ClusterId id = fileSystemManager.getClusterId();
    if (id == null) {
      return "";
    }
    return id.toString();
  }
