If NameNode fails, the entire Hadoop cluster will fail. Actually, there will be no data loss, only the cluster job will be shut down because NameNode is just the point of contact for all DataNodes and if the NameNode fails then all communication will stop.</P> Wed, 02 Dec 2020 05:43:02 GMT sonnu 2020-12-02T05:43:02Z
