Determine Whether to Upgrade or Install an Mpack

Before proceeding, check whether the corresponding Mpack directory is already present.

• If the Mpack directory exists, use the upgrade-mpack command.
• If the Mpack directory does not exist, use the install-mpack command.

cd /var/lib/ambari-server/resources/mpacks

If the directory is present, you can see the following response.

For this upgrade, the Mpack directories for Spark 3.3.3 and Spark 3.5.1 are not present. Therefore, install these Mpacks instead of upgrading them.

Upgrade the Existing Mpacks

Run the following commands for the Mpacks that are already installed:

For example:

ambari-server upgrade-mpack --mpack=ambari-mpacks-spark3.3.3.6.5-1012.tar.gz
ambari-server upgrade-mpack --mpack=ambari-mpacks-pinot-1.4.0.3.3.6.5-1012.tar.gz
ambari-server upgrade-mpack --mpack=ambari-mpacks-kafka3-3.7.2.3.3.6.5-1012.tar.gz
ambari-server upgrade-mpack --mpack=ambari-mpacks-impala-4.4.1.3.3.6.5-1012.tar.gz

Install the Required Mpacks

Install the Mpacks whose corresponding Mpack directories are not present:

For example:

ambari-server install-mpack --mpack=ambari-mpacks-spark3_3.5.1.3.3.6.5-1012.tar.gz
ambari-server install-mpack --mpack=ambari-mpacks-spark3_3.3.3.3.3.6.5-1012.tar.gz

Restart Ambari Server

After you upgrade and install the required Mpacks, restart Ambari Server:

ambari-server restart
