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. {code} 2012-09-25 04:33:20,782 INFO org.apache.hadoop.hdfs.server.datanode.DataNode: For namenode svsrs00127/11.164.162.226:8020 using DELETEREPORT_INTERVAL of 300000 msec BLOCKREPORT_INTERVAL of 21600000msec Initial delay: 0msec; heartBeatInterval=3000 2012-09-25 04:33:20,782 ERROR org.apache.hadoop.hdfs.server.datanode.DataNode: Exception in BPOfferService for Block pool BP-1678908700-11.164.162.226-1342785481826 (storage id DS-1031100678-11.164.162.251-5010-1341933415989) service to svsrs00127/11.164.162.226:8020 java.lang.NullPointerException at org.apache.hadoop.hdfs.server.datanode.BPServiceActor.sendHeartBeat(BPServiceActor.java:434) at org.apache.hadoop.hdfs.server.datanode.BPServiceActor.offerService(BPServiceActor.java:520) at org.apache.hadoop.hdfs.server.datanode.BPServiceActor.run(BPServiceActor.java:673) at java.lang.Thread.run(Thread.java:722) {code} -- This message is automatically generated by JIRA.
