> 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.
