In this scenario, the primary and standby Namenode synchronize metadata information between a set of Journalnode, and a single piece of data is considered successful if it is successfully written to most journalnode. Typically configure an odd number of journalnode there is also a zookeeper cluster configured for ZKFC (Dfszkfailovercontroller) failover, which automatically switches when active Namenode is hung out standby
