Hi All, We are going to setup two clusters(Master-Slave) for disaster recovery. If Custer1 goes down.. HBase client will connect to Slave Custer2, then I can use copyTable command to update Cluster1 tables when it is up again running.
But in case, I loose all my data on Cluster1 !! What is the best/quickest way to bring data from Cluster2(data size will be in TBs)? I will be able to recreate all my tables on Cluster1 with schema stored but using copyTable for >1000 tables does not sound good. Master Cluster : 6-7 nodes (say) Slave Cluster : 2 nodes (with larger disk sizes for data replication from master) Need Advice.
