Hi Wael, I am not sure about moving data in HDFS but you should be able to set up slave without reindexing. Did you start the first node in standalone mode? You need to check if replication handler is enabled (should be by default) and set up slave to pull data from the first node. Note that slave should be placed on a separate host. If you are using HDFS for storing your index and if you can tolerate some downtime, isn’t that enough to satisfy your FT requirement? In master-slave setup you still have SPOF - master node - if it goes out, updates will stop.
