Example 1 with DatanodeDetails

use of org.apache.hadoop.hdds.protocol.DatanodeDetails in project ozone by apache.

the class TestDatanodeUpgradeToScmHA method startPreFinalizedDatanode.

// / CLUSTER OPERATIONS ///

 * Starts the datanode with the first layout version, and calls the version
 * endpoint task to get cluster ID and SCM ID.
 *
 * The daemon for the datanode state machine is not started in this test.
 * This greatly speeds up execution time.
 * It means we do not have heartbeat functionality or pre-finalize
 * upgrade actions, but neither of those things are needed for these tests.
