HBase Java API 问题:put 卡住

搭建好Hbase集群环境，熟悉其基本原理后，下载eclipse后，编写代码，操作hbase API，往Hbase中添加数据，卡在了put。

1.  
   public static void insertData() throws IOException{
2.  
   //put对象 数据插入的操作对象
3.  
   System.out.println("insertData begin");
4.  
   String rowkey="000001";
5.  
   String cf = "C1";
6.  
   String cn = "testdata";
7.  
   String value = "2022/05/12";
8.  
    
9.  
   Put put = new Put(Bytes.toBytes(rowkey));
10.  
    //给put对象赋值
11.  
    put.addColumn(Bytes.toBytes(cf), Bytes.toBytes(cn), Bytes.toBytes(value));
12.  
     
13.  
    //插入数据
14.  
    System.out.println("put begin");
15.  
    table.put(put);
16.  
    System.out.println("put end");
17.  
    //关闭表连接
18.  
    //table.close();
19.  
    System.out.println("insertData end");
20.  
    }

1.  
   conf.set("hbase.zookeeper.quorum", "mu01:2181,cu01:2181,cu02:2181");
2.  
    
3.  
   上面是我的代码段，mu01,cu01,cu02是集群的地址。使用getTable可以获取到Table。当时感觉奇怪，windows怎么会识别这些域名呢，想着表都获取了，就以为没问题了。
4.  
   put的时候出问题了。。。。。。

很长一段时间后，报错新信息如下：

1.  
   org.apache.hadoop.hbase.client.RetriesExhaustedWithDetailsException: Failed 1 action: RetriesExhaustedException: 1 time, servers with issues: null
2.  
   closed success!

上网查询资料，提到hosts文件，才恍然大悟，需要修改windows（windows下安装的eclipse，调用的Hbase java API）下的hosts文件，添加Hbase集群域名地址。windows下的hosts文件路径：  C:\Windows\System32\drivers\etc\hosts
