HBase：Zookeeper告诉远程客户端连接到本地主机

这里超新的HBase/Hadoop。我有一个双节点HBase测试集群正在运行，现在我正尝试从远程Java客户端连接到该集群。这里是我卡住的地方：客户端成功连接到单服务器Zookeeper仲裁（与HBase主服务器运行在同一台服务器上），但Zookeeper传回客户端的地址是localhost，（显然）客户端失败连接到任何东西，因为HBase不在本地运行。考虑到我无法编辑客户端主机文件出于管理的原因（在任何情况下，我不倾向于，因为这似乎是一个可怕的黑客），有没有办法让Zookeeper返回一个适当的IP为HBase主服务器？HBase：Zookeeper告诉远程客户端连接到本地主机

Java代码：

public static final String MASTER_IP = "10.3.248.105"; 
public static final String ZOOKEEPER_PORT = "2181"; 

Configuration config = HBaseConfiguration.create(); 
config.set("hbase.zookeeper.quorum", MASTER_IP); 
config.set("hbase.zookeeper.property.clientPort", ZOOKEEPER_PORT); 

System.out.println("Running connecting test..."); 

try { 
    HBaseAdmin.checkHBaseAvailable(config); 
    System.out.println("HBase found!"); 
    HTable table = new HTable(config, "testTable"); 
    System.out.println("Table testTable obtained!"); 
} catch (MasterNotRunningException e) { 
    System.out.println("HBase connection failed!"); 
    e.printStackTrace(); 
} catch (ZooKeeperConnectionException e) { 
    System.out.println("Zookeeper connection failed!"); 
    e.printStackTrace(); 
} catch (Exception e) { e.printStackTrace(); }

编辑：此外，/ etc/hosts中的主/动物园管理员服务器上的文件：

10.3.248.105 master 
10.3.248.106 slave 
127.0.0.1 localhost

我不不知道这是否是最好的方法，但它应该做到这一点。将主人的主机文件更改为：

10.3.248.105 master  localhost 
10.3.248.106 slave 
#127.0.0.1 localhost

在此更改后重新启动hbase。

成功地让客户端查询'master'而不是'localhost'，但由于'master'没有定义客户端，所以它也无法连接。有没有办法只获取本地IP地址而不是主机名，或者我将不得不建立一个本地DNS或某些东西来处理主机名解析？ –

在ZK的主机文件中做同样的改变，看看它是否有帮助。 – Tariq

Zookeeper和master在同一台服务器上运行，不应该使用相同的hostfile吗？ –
