> During datanode starting, I found some NPE in logs:
> {code:java}
> Caused by: java.lang.NullPointerException: Storage not yet initialized
>     at

>     at 
> org.apache.hadoop.hdfs.server.datanode.DataNode.getVolumeInfo(DataNode.java:3533)

>  {code}
> Because the storage of datanode not yet initialized when we trying to get 
> metrics of datanode, and related code as below:
> {code:java}
> @Override // DataNodeMXBean
> public String getVolumeInfo() {
>   Preconditions.checkNotNull(data, "Storage not yet initialized");
>   return JSON.toString(data.getVolumeInfoMap());
> } {code}
> The logic is ok, but I feel that the more reasonable logic should be return 
> an empty response instead of NPE, because InfoServer will be started before 
> initBlockPool.
