rest - 来自 org.apache.hadoop.hbase.client.HConnectionManager.createConnection 的 InvocationTargetException 异常

Question

由于上述错误，我基于 tomcat 的 REST API 应用程序无法处理请求。到目前为止，我已经尝试过以下事情:

1. 检查所有的jar文件是否可用
2. 检查 tomcat/webapp/ 目录中所有文件的权限
3. 防火墙规则
4. Hbase是否可用

但随后也出现以下异常。我正在使用包含 HBase 0.98.6 的 CDH 5.3.1。有谁知道如何解决这个问题？

尝试建立连接的代码如下:

public class MyDAO {

  protected static HConnection connection;


  static {
      Configuration conf = HBaseConfiguration.create();
      conf.addResource("hbase-site.xml");
      connection = HConnectionManager.createConnection(conf);
      // connection object is still null at this point
    try {
    } catch (Exception ex) {
      ex.printStackTrace();
    }
  }
}

Answer 1

你能试着把它设置到你的 conf 中吗？

config.set("hbase.zookeeper.quorum", "zookeeper-ip:port");

如果这有效，那么我们可以检查您设置到 conf 中的 hbase-site.xml 是否具有正确的详细信息。
