Subject [jira] [Created] (HDFS-5155) Depricate API of getStorageID() and setStorageID() in DatanodeID as multiple storages
Date Sun, 01 Sep 2013 15:15:52 GMT
Junping Du created HDFS-5155:
--------------------------------

             Summary: Depricate API of getStorageID() and setStorageID() in DatanodeID as
multiple storages
                 Key: HDFS-5155
                 URL: https://issues.apache.org/jira/browse/HDFS-5155
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: datanode
    Affects Versions: Heterogeneous Storage (HDFS-2832)
            Reporter: Junping Du
            Assignee: Junping Du


StorageID is an unique number that associates the Datanodes blocks with a particular Datanode.
To enable heterogeneous storage, we are supporting multiple storageIDs per DN, so previous
APIs in DatanodeID, like: getStorageID() and setStorageID(), need to be updated.
