Configuring a Custom Java Home Location

Although not recommended, the Oracle Java Development Kit (JDK), which Cloudera services require, may be installed at a custom location if necessary. These steps assume you have already installed the JDK as documented in Step 2: Install Java Development Kit.

To modify the Cloudera Manager configuration to ensure the JDK can be found:
  1. Open the Cloudera Manager Admin Console.
  2. In the main navigation bar, click the Hosts tab. If you are configuring the JDK location on a specific host only, click the link for that host.
  3. Click the Configuration tab.
  4. Select Category > Advanced.
  5. Set the Java Home Directory property to the custom location.
  6. Click Save Changes.
  7. Restart all services.
