Error:hbase.PleaseHoldException: Master is initializing

今天做了以下HBase的相关安装和配置，启动HBase没有问题，但是使用bin/hbase shell 命令转换到shell下时，使用比如命令，list.、create 'table','col' 等等都会出错，下面贴的是log里面的error部分：

虽然看到了log文档里面的提示，但是由于是刚开始接触HBase，所以还是不知道如何下手。还是上网找各种资源，最后看到官方文档上面说，如果系统是Ubuntu的话，要注意

/etc/hosts里面的127.0.0.1是否是127.0.1.1，如果是的话，把他改过来就可以了。

虽然网上大家的版本各种各样，但是如果真的要学的话，还是官网上面的资料齐全点。
