--------------------------------------
thanks for the work [~maobaolong]
i have gone through your commit .
some questions and suggestions
1)
{quote}// TODO(maobaolong): addCodec for INode and INodeWithAdditionalFields
and all of their sub class.
{quote}
How are you planning to addCodec for INode Objects ?
I think we need to use serialisation and deserialisation of INodeDirectory and
INodeFile
2)
{code:java}
public RocksInodeStore(INodeDirectory rootDir) throws IOException {
DBStore dbStore = DBStoreBuilder.newBuilder(new
OzoneConfiguration()).setName("inode.db")
.setPath(Paths.get("./"))
.build(); {code}
we have to add our INodeTable as
{code:java}
DBStore dbStore = DBStoreBuilder.newBuilder(new
OzoneConfiguration()).setName("inode.db")
.setPath(Paths.get("./")).addTable("inodeTable")
.build();{code}
3) While Intialising RocksINodeStore , First we have to put Root INodeDirectory
into the INodeTable .
