在java中访问远程hbase，masterNotRunning

最近，需要使用HBase作为数据库，所以想研究HBase。但是最近遇到了一个问题，很多天都没有找到答案。 首先描述一下我的机器。一台普通PC机，系统win7，在win7上安装了一台虚拟机，虚拟机运行ubuntu10，使用Hadoop和HBase，它们都运行成功。虚拟机中的HBase外壳和JAVA API成功运行HBase

但问题是，我想使用JAVA API（win7）中的PC机访问hbase，但失败了。 Hbase-site.xml如下所示

<property>
   <name>hbase.cluster.distributed</name>
   <value>false</value>
</property>
<property>
   <name>hbase.tmp.dir</name>
   <value>/opt/tmp</value>
</property>
<property>
   <name>hbase.rootdir</name>
   <value>hdfs://192.168.235.134:9000/hbase</value>
</property>
<property>
   <name>hbase.zookeeper.quorum</name>
   <value>192.168.235.134</value>
</property>

192.168.235.134 localhost ubuntu

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

<property>
   <name>hbase.cluster.distributed</name>
   <value>false</value>
</property>
<property>
   <name>hbase.rootdir</name>
   <value>hdfs://192.168.235.134:9000/hbase</value>
</property>
<property>
   <name>hbase.zookeeper.quorum</name>
   <value>192.168.235.134</value>
</property>

PC（win7）JAVA API hbase-site.xml，如下所示

<property>
   <name>hbase.cluster.distributed</name>
   <value>false</value>
</property>
<property>
   <name>hbase.tmp.dir</name>
   <value>/opt/tmp</value>
</property>
<property>
   <name>hbase.rootdir</name>
   <value>hdfs://192.168.235.134:9000/hbase</value>
</property>
<property>
   <name>hbase.zookeeper.quorum</name>
   <value>192.168.235.134</value>
</property>

192.168.235.134 localhost ubuntu

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

<property>
   <name>hbase.cluster.distributed</name>
   <value>false</value>
</property>
<property>
   <name>hbase.rootdir</name>
   <value>hdfs://192.168.235.134:9000/hbase</value>
</property>
<property>
   <name>hbase.zookeeper.quorum</name>
   <value>192.168.235.134</value>
</property>

出现以下错误：

Org.apache.hadoop.hbase.MasterNotRunningException: com.google.protobuf.ServiceException: java.net.ConnectException: Connection refused: no further information

事实上，我已经看过源代码了，在zookeeper中发现获取主地址总是返回localhost，问题应该在这里。 源代码如下所示。 HConnectionManager.java

private Object makeStubNoRetries() throws IOException, KeeperException, ServiceException {
        ZooKeeperKeepAliveConnection zkw;
        try {
          zkw = getKeepAliveZooKeeperWatcher();
        } catch (IOException e) {
          ExceptionUtil.rethrowIfInterrupt(e);
          throw new ZooKeeperConnectionException("Can't connect to ZooKeeper", e);
        }
        try {
          checkIfBaseNodeAvailable(zkw);

          !----here always return localhost-----------------------!
          ServerName sn = MasterAddressTracker.getMasterAddress(zkw);

          if (sn == null) {
            String msg = "ZooKeeper available but no active master location found";
            LOG.info(msg);
            throw new MasterNotRunningException(msg);
          }
          if (isDeadServer(sn)) {
            throw new MasterNotRunningException(sn + " is dead.");
          }
          // Use the security info interface name as our stub key
          String key = getStubKey(getServiceName(), sn.getHostAndPort());
          connectionLock.putIfAbsent(key, key);
          Object stub = null;
          synchronized (connectionLock.get(key)) {
            stub = stubs.get(key);
            if (stub == null) {
              BlockingRpcChannel channel = rpcClient.createBlockingRpcChannel(sn,
                user, rpcTimeout);
              stub = makeStub(channel);
              isMasterRunning();
              stubs.put(key, stub);
            }
          }
          return stub;
        } finally {
          zkw.close();
        }
      }

我是中国人，英语不好，请原谅。

首先将ip 192.168.235.134添加到win7和 检查端口2181是否在192.168.235.134处打开，如果未打开，则将其打开

要在ubuntu中打开端口，请查看

您还可以添加在客户端中运行的客户端java代码。您是否找到了解决此问题的方法。我也在努力解决同样的问题。请告诉我你的决定。
