Haohui Mai commented on HDFS-5738:
----------------------------------
This patch serializes the inode information into two sections, INODE and
INODE_DIRECTORY. On a high level, the inode information can be seen as a graph,
where the inode are the vertices and the references are the edges. The INODE
section records the information about the inode, such as atime / mtime. The
INODE_DIRECTORY section records the all children for each inode.
The design simplifies the serialization of snapshot information.
