Jing Zhao updated HDFS-5783:
----------------------------
Attachment: HDFS-5783.002.patch
The 001 patch looks good to me. +1
Nit: we should add "if (cluster != null)" before we shutdown the cluster, and
some unused imports can be removed. Since this is trivial, I just made this
change and upload the 002 patch.

> When loading the fsimage, the current code computes its MD5 digest
> on-the-fly. It does not work when the code does not read all the sections in
> strictly sequential order.
> This jira proposes to compute the MD5 digest before loading fsimage.
