服务器hbase-site.xml配置如下:
<configuration>
  <property>
        <name>hbase.rootdir</name>  
        <value>hdfs://localhost:9000/hbase</value>   
    </property>
    <property>
        <name>hbase.cluster.distributed</name>
        <value>true</value>
    </property>
   
</configuration>
启动成功后通过hbase shell能插入表能操作。http://192.168.163.128:16010/master-status可以正常访问

etc/hosts 配置如下
127.0.0.1        localhost
127.0.1.1        hadoop-virtual-machine




客户端代码
  客户端host如下
127.0.1.1   hadoop-virtual-machine


    static {
        conf = HBaseConfiguration.create();
         // 设置Zookeeper,直接设置IP地址
        conf.set("hbase.zookeeper.quorum", "192.168.163.128");



        conf.set("hbase.zookeeper.property.clientPort", "2181");  
      

    }
    public static void createTable(String tableName, String[] family) {
        Admin admin;
        HTableDescriptor table;
        TableName t_name = TableName.valueOf(tableName);
        Connection connection = null;
        try {
            connection = ConnectionFactory.createConnection(conf);
            admin = connection.getAdmin();
            table = new HTableDescriptor(t_name);
            for (int i = 0; i < family.length; i++) {
                table.addFamily(new HColumnDescriptor(family));
            }
           if (admin.tableExists(t_name)) {
                System.out.println("Table Exists!!");
                System.exit(0);
            } else {
                admin.createTable(table);
               System.out.println("Create Table Success!!! Table Name :[ " + tableName + " ]");
            }
            admin.close();
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                if (null != connection && !connection.isClosed()) {
                    connection.close();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
   
    报错如下
