在VB

Question

我在虚拟盒上的Ubuntu中安装了我的hbase。在Windows中，我用java编写了一个程序来检查表是否存在？

@Test
public void checkTableExists() throws IOException
{
    Configuration conf = HBaseConfiguration.create();
    conf.set("hbase.zookeeper.quorum", "192.168.1.3");
    conf.set("hbase.zookeeper.clientPort.property", "2181");
    conf.set("hbse.client.retries.number", "3");
    conf.set("zookeeper.recovery.retry", "2");

    Connection connection = ConnectionFactory.createConnection(conf); 

    Admin admin = connection.getAdmin();

    System.out.println(admin.tableExists(TableName.valueOf("test1")));

    admin.close();
    connection.close();

}

但我没有得到输出。相反，我收到了这个错误：

我哪里错了？
