-------------------------------------

Ozone 1.3.0 had been released and we currently have more than 600 open issues targeted for 1.3.0. I am moving the target field to 1.4.0.

If there is anything needs to be discussed about the Target Version, Please reach out to me via Apache email or Slack.

> As Anu Engineer referenced at DataWorks Summit, if there are huge data, SCM can be separate to multiply SCMs.

> In our scenario, our purpose is using multi-SCMs to manage different datanode group, each SCM can have different type or replication-factor pipeline. OM can get the right related SCM of a key through the key-group map information. We can also transfer files from a scm to another one with the data moving together.
