Registering the HDP 2.4.0 Repo

After you have prepared your cluster for the upgrade, you need to register the HDP 2.4.0 repo. This requires you to perform the following steps:

  1. Update the install.properties file to migrate the database credentials properties and POLICYMGR_EXTERNAL-URL property from HDP 2.3. to HDP 2.4.0.

  2. Change ownership of /etc/ranger/admin/conf/ and /etc/ranger/usersync/conf/ to ranger:ranger:

    chown -R ranger:ranger /etc/ranger/admin/conf/
  3. Install the Ranger Admin component. Be sure to set the JAVA_HOME environment variable if it is not already set.

    cd /usr/hdp/current/ranger-admin/
    
    cp  ews/webapp/WEB-INF/classes/conf.dist/ranger-admin-site.xml
             ews/webapp/WEB-INF/classes/conf/
    
    cp  ews/webapp/WEB-INF/classes/conf.dist/ranger-admin-default-site.xml
            ews/webapp/WEB-INF/classes/conf/
    
    cp  ews/webapp/WEB-INF/classes/conf.dist/security-applicationContext.xml
            ews/webapp/WEB-INF/classes/conf/
    
    ./setup.sh
  4. This should successfully install the Ranger Admin component.

  5. Start the Ranger Admin component.

    service ranger-admin start
  6. You must now configure and setup the Ranger UserSync component by migrating the properties from the HDP 2.3 install.properties file (POLICY_MGR_URL, SYNC_SOURCE and LDAP/AD properties.

  7. Install the Ranger UserSync component. Be sure to set the JAVA_HOME component if it is not already set.

    cd /usr/hdp/current/ranger-usersync/
    
    ./setup.sh
  8. Start the Ranger UserSync component.

    service ranger-usersync start
