Dear folks, I am learning how to take care the disaster recovery situation using Master-Slave replication. Assuming T1:CF1 is the table:colfamily replicated. In the case Master cluster is down(i.e HBASE is down), there are a couple minutes of delta between Master and Slave. From some of the blogs, I read about WALPlayer to sync up Slave so that no(or minimal) data loss.
Is there a step-by-step instruction about how to use WALPlayer in this situation? so that only the delta is replayed? Many thanks Demai
