Step 3: Install the mpack on the Apache Ambari server

Follow the steps below to put the Data Optimizer software in Apache Ambari’s extension cache.

Note: As a best practice, perform the following steps with the same user credentials as the Ambari administrator.

1. Copy the mpack file to a temporary directory on the Ambari server, for example /tmp/pdso-mpack-1.0.0.0.tar.gz

2. Connect to the Ambari server using a Secure Shell (SSH) protocol.

3. Install the mpack with the following command, updated for your mpack location: ambari-server install-mpack --verbose --mpack=/tmp/pdso-mpack-1.0.0.0.tar.gz

4. Restart the Ambari server.

   This step refreshes Ambari server’s stale memory cache so it recognizes the Data Optimizer extension.
