Subject [jira] [Commented] (HDFS-7240) Object store in HDFS
Date Thu, 16 Oct 2014 22:59:38 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7240?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14174416#comment-14174416

Jitendra Nath Pandey commented on HDFS-7240:
--------------------------------------------

I think HDFS-5477 takes us towards making the block management service generic enough to support
different storage semantics and API. In that sense object store will be one more use case
for the block management. The object store design should work with the block management service.

> 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.
