Uses of ReplicaInfo in org.apache.hadoop.hdfs.server.datanode

Subclasses of ReplicaInfo in org.apache.hadoop.hdfs.server.datanode

Modifier and Type	Class	Description
class	FinalizedProvidedReplica	This class is used for provided replicas that are finalized.
class	FinalizedReplica	This class describes a replica that has been finalized.
class	LocalReplica	This class is used for all replicas which are on local storage media and hence, are backed by files.
class	LocalReplicaInPipeline	This class defines a replica in a pipeline, which includes a persistent replica being written to by a dfs client or a temporary replica being replicated by a source datanode or being copied for the balancing purpose.
class	ProvidedReplica	This abstract class is used as a base class for provided replicas.
class	ReplicaBeingWritten	This class represents replicas being written.
class	ReplicaUnderRecovery	This class represents replicas that are under block recovery It has a recovery id that is equal to the generation stamp that the replica will be bumped to after recovery The recovery id is used to handle multiple concurrent block recoveries.
class	ReplicaWaitingToBeRecovered	This class represents a replica that is waiting to be recovered.
