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 :9000</value>
</property>
重启hadoop，在进入hive查询即可
