hbase排错:be reached after 1 tries, giving up.

1.hbase错误日志提示hadoop建议用master，于是修改了hadoop的配置文件core-site.xml，把其中的内容修改为：<value>hdfs://master:9000/</value>
2.hbase的master不能连接10.10.10.168的60020端口。修改10.10.10.168中的/etc/hosts(保持提供的不变，)，添加

错误日志如下所示：

-------------------------------------------------------------------------------------------------------------------
11/06/17 22:25:07 INFO ipc.HbaseRPC: Server at /10.10.10.168:60020 could not be reached after 1 tries, giving up.

添加的内容如下
-------------------------------------------------------------------
10.10.10.167 master
10.10.10.168 slave1
10.10.10.169 slave2
