Hello Hadoopers, I am planning for a Disaster Recovery(DR) project mainly for *hadoop clusters*. Infrastructure is in a DataCenter in West say DC1 . I Have created a backup hadoop-spark cluster in DataCenter in east say DC2. With Distcp will keep DC2 synchd with DC1 . This will work as DR .
But what I want is that in case when DC1 went down completely, the automatic failover should happen and without any or very very less downtime DC2 is live. I have configured *hadoop high availability* and *Automatic Failover *in hadoop cluster in DC1 and it works fine. But that won't help in case whole DC1 goes down. Is there a solution where I can keep two hadoop clusters running in parallel, completely synchd, in two different DataCenters. In case hadoop cluster in DC1 goes down , Automatic failover occurs to DC2. Any hint would be of great help, any feedback, positive or negative, will be a great help. Thanks .
