最近公司项目需要用到Hbase数据库，在学习过程中，用java API连接数据库的过程中出现了RpcRetryingCaller Call exception问题，Log日志显示多次连接Hbase数据库失败（实际上应该是请求Zookeeper服务器），如下所示：

MINAServer Logger--> INFO{RpcRetryingCaller.java:120}-Call exception, tries=10, retries=35, retryTime=68227ms, msg=row 'user,9,99999999999999' on table 'hbase:meta' at region=hbase:meta,,1.1588230740, hostname=Dev6-BOCSS-03,60020,1498029505361, seqNum=0

我最后的解决方法如下：

需要在java开发时使用的系统hosts问价下同样配置数据库系统相同的节点。如下图中红框内部分，java开发的windows环境hosts文件要与数据库所在的linux服务器系统上hosts的配置匹配。这样做解决了我的问题。
