   > Thanks the patch @lamber-ken. It looks good to me. As far as I remember we 
agreed to keep the vendor neutral interface, but support only rocksdb for now.
   > 
   > Some minor comments:
   > 
   > Can you please remove the `org.fusesource.leveldbjni` dependency from the 
pom files if it's no longer required?
   > 
   > `MetadataStore` is an old interface and replaced by `DBStore` everywhere 
(the later can support multiple column families).
   > 
   > Which means that:
   > 
   > 1. `RocksDBStore`, `RocksDBStoreIterator`, `MetadataStore` and 
`MetadataStoreBuild` can also be removed (IMHO)
   > 2. `SQLCLI` can be removed because the functionality is replaced by `ozone 
debug ldb`.
   > 3. As `MetdataStore` is not required, the related Genesis tests can be 
removed `BencMark...` files
   > 
   > I would suggest including at least the dependency update in this 
patch(unless leveldb is really required by any other code, it can be removed 
from `pom.xml`)
   > 
   > 1 + 3 and 2 can be included in this patch or followup patches... Depends 
on from your preference.
   
   sure, will do, thanks.
