Hi
I wonder how HDInsight fault tolerance is working.
There are availability zones in each region, so I believe HDInsight's head nodes and worker nodes are spanned over these availability zones, but it's true?
No matter how hard the failover works, if the head nodes are located in the same availability zone and system failure happened in the zone, all the head nodes will not be working.
I am worried about the same situation as worker nodes.
Please, give me some answer.
Thanks.
