pls update ...
In our organization, we have hadoop cluster with 13 data nodes and replication factor-2. But we have been facing issue wrt HDD for last two months. There are cases where 3-4 disks are faulty together, leading to data loss.
Now, we want to set-up separate geographical cluster. Need to know how to synchronize data between these two clusters. Connectivity would not be an issue. But incremental data need to be copied on other cluster.
