分布式方式部署的HBase，啟動正常，Shell操作正常，使用HBase的Java Api操作時總是連接失敗，信息如下：
This server is in the failed servers list: localhost.localdomain/202.102.110.204:60000
HBase部署在192.168.100.28，IP地址變掉了原因在於DNS解析，
臨時解決辦法，可以在調用Api的客戶端機器上的hosts文件中加上一條記錄
192.168.100.28 localhost.localdomain
將
localhost.localdomain指向部署HBase的機器。
運行結果正常，如下：
