3 - Use case

A superuser wants to submit job and access hdfs on behalf of a user. The superuser has kerberos credentials but the user doesn’t have any.

4 - Configuration

Example: Hadoop - core-site.xml

core-site.xml
<property>
     <name>hadoop.proxyuser.super.hosts</name>
     <value>host1,host2</value>
   </property>
   <property>
     <name>hadoop.proxyuser.super.groups</name>
     <value>group1,group2</value>
</property>

where:

  • super is the admin user
  • hadoop.proxyuser.super.hosts defines the host where the admin user super can connect to impersonate.
  • hadoop.proxyuser.super.groups defines the group that can be impersonated.
