-------------------------------------
[~brahmareddy], thank you for telling me about HDFS-7784. I guess it's kind of
the same optimization as I have thought. Since I have finished a patch which
implemented a pipeline model for this kind of stuff, I'd like to post the patch
here for reference.

> Key: HDFS-13700
> URL: https://issues.apache.org/jira/browse/HDFS-13700
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: zhouyingchao
> Priority: Major
>
> The process of loading a file system image involves reading inodes section,
> deserializing inodes, initializing inodes, adding inodes to the global map,
> reading directories section, adding inodes to their parents' map, cache name
> etc. These steps can be done in a pipeline model to reduce the total
> duration.
