> {{TestDatanodeUpgradeToScmHA}} was the first unit test for handling of a specific datanode layout version. It works by starting just the minimal [SCM RPC server|https://github.com/apache/ozone/blob/6ed1e58dd598e4dbc8948e1c23ae67dd1e55104c/hadoop-hdds/container-service/src/test/java/org/apache/hadoop/ozone/container/upgrade/TestDatanodeUpgradeToScmHA.java#L561] and running datanodes without their [heartbeat thread|https://github.com/apache/ozone/blob/0c47b0f3bfaf39f1625295a2631c21276c48b9f8/hadoop-hdds/container-service/src/main/java/org/apache/hadoop/ozone/container/common/statemachine/DatanodeStateMachine.java#L331]. This allows most fo the functionality that would be present in a MiniOzoneCluster integration test but runs at the speed of a unit test.
> The framework has since been adopted for testing other layout features in {{TestDatanodeUpgradeToSchemaV3}} and {{TestDatanodeUpgradeToHBaseSupport}}, but the code has been copied each time. This Jira is to extract the common setup code so that it can be re-used to test datanode layout features in the future.
