> Datanode return empty response instead of NPE for GetVolumeInfo during

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

> org.apache.hadoop.thirdparty.com.google.common.base.Preconditions.checkNotNull(Preconditions.java:899)

> com.sun.jmx.mbeanserver.ConvertingMethod.invokeWithOpenReturn(ConvertingMethod.java:175)
> {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.
