Arpit Agarwal commented on HDDS-759:
------------------------------------
Preliminary v01 patch:
- Move OZONE_METADATA_DIRS setting to HddsConfigKeys, since it is also read by
HDDS services. This triggered cascading changes to numerous unit tests, hence
the large patch size.
- Added ozone.scm.db.dirs and ozone.om.db.dirs settings for SCM and OM
respectively. Both fallback to OZONE_METADATA_DIRS.
> Create config settings for SCM and OM DB directories

> 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.
> To avoid disruption, we can have them fallback to {{ozone.metadata.dirs}}.
