------------------------------

             Summary: hadoop.proxyuser.mapr.groups does not work to restrict the groups that can be impersonated
                 Key: HIVE-11029
                 URL: https://issues.apache.org/jira/browse/HIVE-11029
             Project: Hive
          Issue Type: Bug
          Components: HiveServer2
    Affects Versions: 1.2.0, 1.0.0, 0.14.0, 0.13.0
            Reporter: Na Yang
            Assignee: Na Yang


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.
