> Project: Hadoop HDFS

> Reporter: lujie

> Attachments: HDFS-14372_0.patch, HDFS-14372_1.patch

> Take the code BPServiceActor#register:
> {code:java}
> while (shouldRun()) {
> try {
> // Use returned registration from namenode with updated fields
> newBpRegistration = bpNamenode.registerDatanode(newBpRegistration);
> newBpRegistration.setNamespaceInfo(nsInfo);
> bpRegistration = newBpRegistration;
> break;
> } catch(EOFException e) { // namenode might have just restarted
> ....
> }
> LOG.info("Block pool " + this + " successfully registered with NN");
> bpos.registrationSucceeded(this, bpRegistration);
> {code}
> if DN is shutdown, then above code will skip the loop, and bpRegistration ==
> null, the null value will be used in DataNode#bpRegistrationSucceeded:
> {code:java}
> if(!storage.getDatanodeUuid().equals(bpRegistration.getDatanodeUuid()))
> {code}
> hence NPE happens
> {code:java}
> java.lang.NullPointerException
> at
> org.apache.hadoop.hdfs.server.datanode.DataNode.bpRegistrationSucceeded(DataNode.java:1583)
