Arpit Agarwal updated HDFS-4985:
--------------------------------
Attachment: h4985.05.patch
Thanks Nicholas. I just removed the UNKNOWN/DEFAULT enum from StorageTypeProto.
On further thought it is an optional field so we can just skip sending it over
the wire if unknown/default. StorageType and StorageTypeProto can be in sync
and they are both in the hdfs package now.
> Add storage type to the protocol and expose it in block report and block
> locations

> 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.
