Ayush Saxena commented on HDFS-15133:
-------------------------------------
[~maobaolong] are you just trying to push just the inodeMap to the DB? Pushing
just the inodeMap wouldn't be of much use. Ideally we need to push all the
inodes with all its fields into the db, so as to ensure storing max objects.
> Use rocksdb to store NameNode inode and blockInfo
