             Summary: Datanode should allow choosing the target storage
                 Key: HDFS-5157
                 URL: https://issues.apache.org/jira/browse/HDFS-5157

          Issue Type: Sub-task
          Components: datanode
    Affects Versions: Heterogeneous Storage (HDFS-2832)
            Reporter: Arpit Agarwal


Datanode should allow should choosing a target Storage or target Storage Type as a parameter
when creating a new block. Currently there are two ways in which the target volume is chosen
(via {{VolumeChoosingPolicy#chooseVolume}}.
# AvailableSpaceVolumeChoosingPolicy
# RoundRobinVolumeChoosingPolicy

BlockReceiver and receiveBlock should also accept a new parameter for target storage or storage
type.
