Hbase 表未列出

Question

我创建了一个示例 java 程序来在 HBase 中创建一个表，它显示成功创建了表。但是当我打开我的 HBase 终端并使用命令 list 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);

其中192.168.1.47:60000是Hbase所在的地方。

编辑后：

我试过了，现在它也给了我一个错误，

上述代码中你还没有创建表，你只提供了名称和架构信息。

请在打印“完全创建成功”之前添加以下行 -

hbase.createTable(desc);
