java - 无法在远程HBase表中插入记录

Question

我试图在htable中插入一条记录。该程序没有结束，但是在打印111之后挂起。请帮助。

public static void insert(){
    org.apache.hadoop.conf.Configuration config = HBaseConfiguration.create();
    HTable table = null;
    try{
    config.set("hbase.zookeeper.quorum","ip_address_of_remotemachine");
    config.set("hbase.zookeeper.property.clientPort","2181");
    config.set("hbase.master", "hdfs://remote_ip:2181/hbase");
    table = new HTable(config, "table_A");
    Put p = new Put(Bytes.toBytes("1"));
    p.add(Bytes.toBytes("Col"), Bytes.toBytes("ColFamily1"), Bytes.toBytes("Test123"));
    System.out.println("111");
    table.put(p);
    System.out.println("222");
    table.setAutoFlush(true);
    }
    catch(IOException ee){
        ee.printStackTrace();
    }
    catch(Exception e){
        e.printStackTrace();
    }
    finally{
        try {
            if(table != null)
            table.close();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

}

我得到的输出为

您需要将群集的hbase-site.xml文件放入Java应用程序的类路径中。
另外，您需要删除设置配置对象的代码。也就是说，这些行:

config.set("hbase.zookeeper.quorum","ip_address_of_remotemachine");
config.set("hbase.zookeeper.property.clientPort","2181");
config.set("hbase.master", "hdfs://remote_ip:2181/hbase");
