--------------------------------
[~xuefuz], that is correct. The problem happens on unsecured cluster. Thanks.
> hadoop.proxyuser.mapr.groups does not work to restrict the groups that can be
> impersonated

> In the core-site.xml, the hadoop.proxyuser.<user>.groups specifies the user
> groups which can be impersonated by the HS2 <user>. However, this does not
> work properly in Hive.
> In my core-site.xml, I have the following configs:
> <property>
> <name>hadoop.proxyuser.mapr.hosts</name>
> <value>*</value>
> </property>
> <property>
> <name>hadoop.proxyuser.mapr.groups</name>
> <value>root</value>
> </property>
> I would expect with this configuration that 'mapr' can impersonate only
> members of the Unix group 'root'. However if I submit a query as user 'jon'
> the query is running as user 'jon' even though 'mapr' should not be able to
> impersonate this user.
