Examples with CLOSED org.apache.hadoop.hdds.protocol.proto.StorageContainerDatanodeProtocolProtos.ContainerReplicaProto.State.CLOSED used on opensource projects

Example 1 with CLOSED

use of org.apache.hadoop.hdds.protocol.proto.StorageContainerDatanodeProtocolProtos.ContainerReplicaProto.State.CLOSED in project ozone by apache.
