Description

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.
