             Summary: NPE in BPServiceActor#sendHeartBeat
                 Key: HDFS-4201
                 URL: https://issues.apache.org/jira/browse/HDFS-4201
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: name-node
            Reporter: Eli Collins


Saw the following NPE in a log.

Think this is likely due to {{dn}} or {{dn.getFSDataset()}} being null, (not {{bpRegistration}}) due to a configuration or local directory failure.
