  • Class
    Description
    org.apache.hadoop.hdfs.shortcircuit.ClientMmap
    A reference to a memory-mapped region used by an HDFS client.
    org.apache.hadoop.hdfs.shortcircuit.DfsClientShm
    DfsClientShm is a subclass of ShortCircuitShm which is used by the DfsClient.
    org.apache.hadoop.hdfs.shortcircuit.DfsClientShmManager
    Manages short-circuit memory segments for an HDFS client.

    DomainSocketFactory.PathState
     
    org.apache.hadoop.hdfs.shortcircuit.ShortCircuitCache
    The ShortCircuitCache tracks things which the client needs to access HDFS block files via short-circuit.

    org.apache.hadoop.hdfs.shortcircuit.ShortCircuitCache.ShortCircuitReplicaCreator
     
    org.apache.hadoop.hdfs.shortcircuit.ShortCircuitReplica
    A ShortCircuitReplica object contains file descriptors for a block that we are reading via short-circuit local reads.

    org.apache.hadoop.hdfs.shortcircuit.ShortCircuitShm
    A shared memory segment used to implement short-circuit reads.
    org.apache.hadoop.hdfs.shortcircuit.ShortCircuitShm.ShmId
    Identifies a DfsClientShm.
    org.apache.hadoop.hdfs.shortcircuit.ShortCircuitShm.SlotId
    Uniquely identifies a slot.
