The remaining cluster services will continue to run. That way when the namenode (or other failed processes) is restored the cluster will resume healthy operation. This is part of hadoop’s ability to handle network partition events.

Hi, What happens if name node has crashed for more than one hour but secondary name node, all the data nodes, job tracker, task trackers are running fine? Do those daemon services also automatically shutdown after some time? Or those services keep running hoping for namenode to come back? Regards, Chandrash3khar Kotekar Mobile - +91 8600011455
