进入 $hadoop_home vi conf/core-site.xml

之前配置是：

<property>

<name>fs.default.name</name>

<value>hdfs://172.16.27.115:9000</value>

</property>

查看vim /etc/hosts

172.16.27.115 namenode115

修改core-site.xml中ip为hostname

<property>

<name>fs.default.name</name>

<value>hdfs://namenode115<wbr>:9000&lt;/value&gt;</wbr>

</property>

重启hadoop，在进入hive查询即可
