Jitendra Nath Pandey commented on HDFS-7240:
--------------------------------------------
bq. Why an object store as part of HDFS?
It is one of the goals to have both hdfs and ozone being available in the same
deployment. That means same datanodes serve both ozone and hdfs data.
Therefore, having ozone as a separate subproject in hadoop is ok as long as
they can share the storage layer. The datanode changes would still be needed in
hdfs.
There is another proposal in HDFS-10419, that moves HDFS data into storage
containers. I think that effort will need a new datanode implementation, that
shares storage container layer with ozone.

> This jira proposes to add object store capabilities into HDFS.
> As part of the federation work (HDFS-1052) we separated block storage as a
> generic storage layer. Using the Block Pool abstraction, new kinds of
> namespaces can be built on top of the storage layer i.e. datanodes.
> In this jira I will explore building an object store using the datanode
> storage, but independent of namespace metadata.
> I will soon update with a detailed design document.
