As you can see in the previous blog , Hadoop successfully failover , but it fails to failback.
Our solution to this problem is this:
The failover will be done as described in the post a couple of days ago.
The failback will have to be done manually (it makes sense , as we will probably need to figure out why the server crushed in the first place)
I will update about the specifics as soon as we have it settled , and I’ll do my best to document the testing and integration process.
