问题
java连接hbase卡住
这个过程会持续一段时间
log4j:WARN No appenders could be found for logger (org.apache.hadoop.security.Groups).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
然后就报了异常信息端口无法映射这个端口的错误

解决
看了下linux系统下的/etc/hosts 文件
里面有一段配置
192.168.61.128 node1（IP地址 域名）
将这个配置配置到本地windows或者mac系统下的
C:\Windows\System32\drivers\etc\hosts（windows）
/hosts（mac注意切换成超级管理员登录终端才能修改hosts文件）
调试运行成功
