Steve Loughran commented on HDFS-7240:
--------------------------------------
cluster level
# is there a limit on the #of storage volumes in a cluster? does GET/ return
all of them?
Storage Volume Level
# any way to enum users? e.g. GET /admin/user/
#
Bucket Level
# what if I want to GET the 1001st entry in an object store? GET spec doesn't
allow this.
# Propose: listing of entries to be a structure that includes length, block
sizes, everything to be rebuild into a FileStatus
Object level
# GET on object must support ranges
# HEAD should supply content-length
> Object store in HDFS

> 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.
