Example 1 with DECOMMISSIONED

use of org.apache.hadoop.hdds.protocol.proto.HddsProtos.NodeOperationalState.DECOMMISSIONED in project ozone by apache.

the class TestReplicationManager method testOverReplicatedClosedContainerWithDecomAndMaint.

/**
 * When a CLOSED container is over replicated, ReplicationManager
 * deletes the excess replicas. While choosing the replica for deletion
 * ReplicationManager should not attempt to remove a DECOMMISSION or
 * MAINTENANCE replica.
