@tomscut Thanks for the explanation. When `nodeID` is DatanodeRegistration
(I think it is most likely case), `DatanodeRegistration#toString()` is most
informative.
`nodeID.getDatanodeUuid()`:
```
BLOCK* processReport 0x51eb6427619ccf8f: Processing first storage report for
DS-ced48a3c-7e37-4a94-9cf9-404e07e659a7 from datanode
a7a8fd2f-e0cd-40a4-8fcd-65760b6bc6e6
```
`nodeID.getXferAddrWithHostname()`:
```
BLOCK* processReport 0x5006fb6a4251db51: Processing first storage report for
DS-ced48a3c-7e37-4a94-9cf9-404e07e659a7 from datanode hostname:11001
```
`nodeID`:
```
BLOCK* processReport 0xe518c3bd634f15e6: Processing first storage report for
DS-0048bf1d-84da-444c-8c3f-251dab39f1dc from datanode
DatanodeRegistration(127.0.0.1:11000,
datanodeUuid=64886279-5799-47a6-96ba-653e3675e816, infoPort=11020,
infoSecurePort=0, ipcPort=11010,
storageInfo=lv=-57;cid=CID-130467d5-c200-4869-9330-d9eedf4f3909;nsid=930729152;c=1635316881247)
```
So just using `nodeID` looks good to me.
> because changing the toString() of the datanodeID or DatanodeRegistration
might cause other compatibility issues.
I agreed. Let's keep it as it was.
