Description

When ozone is enabled and HddsDatanodeService plugin is configured, datanode should load HddsDatanodeService plugin and start Hdds services. We have to add unit test case inside hadoop/hadoop-ozone/integration-test using MiniDFSCluster to verify the following scenarios

• HddsDatanodeService is loaded as part of datanode startup.
• run Freon test against MiniDFSCluster and validate the data that has been written.
