Does anyone know what the parameter dataReplicationFactor in Apache IoTDB is for? When I tried to startup IoTDB, an error reported that the dataReplicationFactor setting in DataNode was wrong. I don't understand what this parameter means, so anyone can explain this to me, and suggest any possible reason that this parameter may be wrong?
This dataReplicationFactor in Apache IoTDB is used to set the number of consensus copies of the DataNodes. You can check whether the version of the cluster IoTDB is consistent for each server, and whether there is data in the data directory before starting. The error you met may because the DataNode is not started successfully. You can try to clear the log files and then restart IoTDB, and you should know the specific reason by looking through the logs. Also, make sure there is no data directory at startup.
