You have to configure 2 files for this.
hive-site.xml
<property>
<name>hive.server2.enable.impersonation</name>
<description>Enable user impersonation for HiveServer2</description>
<value>true</value>
</property>
In hdfs configuration, core-site.xml
<property>
<name>hadoop.proxyuser.hive.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hive.groups</name>
<value>*</value>
</property>
This should work.
