[jira] [Created] (HDFS-4985) Add storage type to the protocol and expose it in block report and block locations

Suresh Srinivas created HDFS-4985:
-------------------------------------

             Summary: Add storage type to the protocol and expose it in block report and block locations
                 Key: HDFS-4985
                 URL: https://issues.apache.org/jira/browse/HDFS-4985
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: datanode, namenode
            Reporter: Suresh Srinivas


With HDFS-2880 datanode now supports storage abstraction. This is to add storage type in to the protocol. Datanodes currently report blocks per storage. Storage would include storage type attribute. Namenode also exposes the storage type of a block in block locations.
