Re: How do I recover the namenode?
This is not recommended.
You only backup the fsimage file, the data blocks, which are stored in
datanode, are not stored.
The chances may be if you removed some file after your fsimage backup,
those data blocks belonging to this file will be removed from all
datanodes; in this case, your namenode will report that blocks are missing;

1. Since you're using HA, lots of the editlogs are stored in the journal
node; the fsimage you have may not be exactly the one you want;
