Subject [jira] [Commented] (HDFS-7240) Object store in HDFS
Date Mon, 06 Nov 2017 17:29:01 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7240?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16240584#comment-16240584

stack commented on HDFS-7240:

The posted document needs author, date, and ref to this issue. Can it be made a google doc
so can comment inline rather than here?

I skipped to the end, "So​ ​why​ ​put​ ​the​ ​Ozone​ ​in​ ​HDFS​
​and​ ​not​ ​keep​ ​it​ ​a​ ​separate​ ​project". There is no argument
here on why Ozone needs to be part of Apache Hadoop. As per [~shv] above, Ozone as separate
project does not preclude its being brought in instead as a dependency nor does it dictate
the shape of deploy (Bullet #3 is an aspiration, not an argument).

> 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.
