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. > Object store in HDFS > -------------------- > > Key: HDFS-7240 > URL: https://issues.apache.org/jira/browse/HDFS-7240 > Project: Hadoop HDFS > Issue Type: New Feature > Reporter: Jitendra Nath Pandey > Assignee: Jitendra Nath Pandey > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
