在idea运行hbase创建表的代码，出现运行要很长时间的情况，最后出现以下错误：
log4j:WARN No appenders could be found for logger (org.apache.hadoop.util.Shell).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

有可能某个节点宕掉了，请用jps查看节点服务是否完整
如果不是节点服务问题，就有可能是你在C:WindowsSystem32driversetchost没有添加映射，即是虚拟机中配置Hadoop集群的/etc/host的内容
或者把提取出来的配置文件里的节点名字改成ip，一定不可以直接使用节点名字！！！
例如
