Upgrading the Cloudera Navigator Data Management Component

Minimum Required Role: Navigator Administrator (also provided by Full Administrator)

Upgrade Notes

  • 2.4
    • Cloudera Navigator no longer supports JDK 1.6. If you are using JDK 1.6, you must upgrade to JDK 1.7 or 1.8. See Java Development Kit Installation.
    • The Cloudera Navigator Metadata Server requires an upgrade of data in the storage directory. See Upgrade Procedure.
  • 2.2 - Policies created with Cloudera Navigator 2.1 (containing the Beta version policy engine) are not retained when upgrading to Cloudera Navigator 2.2.
  • 2.1 - When you upgrade to Cloudera Navigator 2.1 or higher from Navigator 2.0 or lower, the upgrade wizard adds a database for the Navigator Metadata Server. This is a different database than the currently existing Navigator Audit Server database.
  • 2.0 - Cloudera does not provide an upgrade path from the Navigator Metadata Server which was a beta release in Cloudera Navigator 1.2 to the Cloudera Navigator 2 release. If you are upgrading from Cloudera Navigator 1.2 (included with Cloudera Manager 5.0), you must perform a clean install of Cloudera Navigator 2. Therefore, if you have Cloudera Navigator roles from a 1.2 release:
    1. Delete the Navigator Metadata Server role.
    2. Remove the contents of the Navigator Metadata Server storage directory.
    3. Add the Navigator Metadata Server role according to the process described in Adding the Navigator Metadata Server.
    4. Clear the cache of any browser that had used the 1.2 release of the Navigator Metadata component. Otherwise, you may observe errors in the Navigator Metadata UI.

Before Upgrading

  1. Stop the Navigator Metadata Server role.
  2. Back up the Navigator Metadata Server storage directory.
  3. Make sure that the Navigator Metadata Server has sufficient memory to complete the upgrade.
  4. If you are using an Oracle database, in SQL*Plus, set the following additional privileges:
    GRANT EXECUTE ON sys.dbms_crypto TO nav;
    GRANT CREATE VIEW TO nav;
    where nav is the user of the Navigator Audit Server database.
