Thomas Demoor commented on HDFS-7240:
-------------------------------------
[~john.jian.fang] and [~jnp]:
* Avoiding rename happens in [HADOOP-9565] by introducing ObjectStore (extends
Filesystem) and letting FileOutputCommitter, Hadoop CLI, ... act on this (by
avoiding rename). Ozone could easily extend ObjectStore and benefit from this.
* [HADOOP-11262] extends DelegateToFileSystem to implement s3a as an
AbstractFileSystem and works around issues as modification times for
directories (cfr. Azure).

> 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.
