Hbase create 'test','cf' 报错！?报错

小弟刚开始研究Hbase  ,单机版，按着官网的步骤，一步一步配置 ，但走到用shell 命令创建表时出了问题？都研究一天了，还是不足的哪里有配置不对的地方 ，往大神们指点一二。跪求！！

hbase-site.xml 配置文件里的信息

<configuration>
<property>
    <name>hbase.rootdir</name>
  <value>/home/phz/config/hbase</value>
  </property>
<property>
   <name>hbase.zookeeper.quorum</name>
   <value>localhost</value>
</property>

<property>
   <name>hbase.zookeeper.property.clientPort</name>
   <value>2181</value>
</property>
</configuration>

log 文件内容，我copy关键信息

Caused by: java.net.UnknownHostException: phz-Lenovo: phz-Lenovo  好像报错的地方在这里 ，但不知道是哪儿配置的问题
