Installing Atlas using the Cloudera Manager upgrade wizard
You can use the wizard in Cloudera Manager to upgrade from CDH to CDP Private Cloud Base, install Apache Atlas and its dependencies, and to generate customized commands to initiate the migration phases.
This page describes the Cloudera Manager wizard steps that help you to set up Atlas and its service dependencies.
When a cluster is upgraded from CDH 5 or CDH 6 to CDP 7.x, by default the atlas.metadata.namespace property is set to cm.
If a different namespace property needs to be set, for example: cluster1, the same needs to be set while running the nav2atlas script as "-clusterName '' parameter and also in the atlas-application properties in the upgrade wizard.
Post-upgrade, note that the different value "cluster1" is not automatically updated in Hooks for services like Hive, HBase, Impala, Spark, and Kafka. You must make sure that before you upgrade your cluster and after the services are installed, you must set the value "cluster1" for all the available services. And later complete the upgrade process.
As an example process, follow these steps if namespace other than default "cm" needs to be set:
To return to the main wizard documentation, go to Upgrading a CDH 6 Cluster.
Follow instructions in the upgrade wizard "Install Services" section.
