> Currently SCM, OM and DN all use {{ozone.metadata.dirs}} for storing
> metadata.
> Looking more closely, it appears that SCM and OM have no option to choose
> separate locations. We should provide custom config settings. For most
> production clusters, admins will want to carefully choose where they place OM
> and SCM metadata, similar to how they choose locations for NN metadata.
> To avoid disruption, we can have them fallback to {{ozone.metadata.dirs}}.
