> Ideally we should have the same source code reading the fsimage file and then
> using different visitors to process deserialized data. I think we can achieve
> that goal by implementing a LoadFSImageVisitor, which will call FSNamesystem
> methods to add inodes to the directory tree and so on, making it a
> replacement to FSImage.loadFSImage().
> The LoadFSImageVisitor can be passed to FSImageProcessor same as other
> visitors Jakob implemented.
> We can do it in a separate Jira, but it should be done before the next
> release so that we had uniform deserialization in the release.
> This approach will probably also require to move FSImageProcessor code inside
> server.namenode package. The OfflineImageViewer itself should remain in tools.

> This work never got done, and it caused a problem in HDFS-1435. This JIRA is
> to track that work.
