java - Hbase表未列出

Question

我已经创建了一个示例Java程序来在HBase中创建一个表，它显示成功创建了该表。但是当我打开HBase终端并使用list命令时，创建的表不存在。为什么会这样？我的代码如下

    Configuration config = HBaseConfiguration.create();
    conf.set("hbase.master","192.168.1.47:60000");
       Configuration config = HBaseConfiguration.create();
         config.set("hbase.zookeeper.quorum", "192.168.1.47");
         config.set("hbase.zookeeper.property.clientPort", "2181");
         config.set("hbase.master", "192.168.1.47:60000");
         config.set("zookeeper.znode.parent", "/hbase-unsecure");
    HBaseAdmin hbase = new HBaseAdmin(conf);

    HTableDescriptor desc = new HTableDescriptor("sample");
    HColumnDescriptor meta = new  ColumnDescriptor("samplecolumn1".getBytes());
    desc.addFamily(meta);
    System.out.println( "Created Success fully..." );

hbase.createTable(desc);
192.168.1.47:60000是Hbase所在的位置。

编辑后:

我也尝试了一下，这给了我一个错误，

您尚未在上面的代码中创建表，仅提供了名称和架构信息。

在添加“完全创建成功”之前，请添加以下行-

hbase.createTable(desc);
