Question

我正在尝试与非分布式模式下配置的HBase建立远程连接。我的代码在java playframework中是以下代码：

    // Instantiating a configuration class
    Configuration hbaseConfiguration = HBaseConfiguration.create();
    try {
        Configuration newConfig = new Configuration(hbaseConfiguration);
        newConfig.set("hbase.zookeeper.quorum", "77.154.69.181");
        newConfig.set("hbase.zookeper.property.clientPort", "2181");
        HConnection connection = HConnectionManager
                .getConnection(newConfig);
       HBaseAdmin hBaseAdmin = new HBaseAdmin(connection);
        if (!hBaseAdmin.isMasterRunning())
            throw new Exception("Hbase is not running");
    } catch (Exception e) {
        e.printStackTrace();
    }

我收到以下错误：

    [error] org.apache.hadoop.hbase.MasterNotRunningException: com.google.protobuf.ServiceException: org.apache.hadoop.net.ConnectTimeoutException: 10000 millis timeout while waiting for channel to be ready for connect. ch : java.nio.channels.SocketChannel[connection-pending remote=vm-77446.localdomain/77.154.69.181:37027]

Answer 1

    newConfig.set("hbase.zookeper.property.clientPort", "2181");

应该是

    newConfig.set("hbase.zookeeper.property.clientPort", "2181");

你的代码中有拼写错误。

Answer 2

从此＆＃34; org.apache.hadoop.hbase.MasterNotRunningException＆＃34;，您的hbase主服务器（HMaster）未运行。尝试从浏览器打开http://MasterIp:60010并检查您的主服务器是否正在运行（应列出包含表名的Hbase主页）。

如果master正在运行，请添加

    newConfig.set("hbase.master","MasterIP:60000");

正下方

   newConfig.set("hbase.zookeeper.property.clientPort", "2181");

连接到hbase时出错
