Jing Zhao commented on HDFS-9319:
---------------------------------
Yeah, originally I planned to first make DatanodeInfo thread safe then maybe
DatanodeDescriptor. In this way we can break some global lock protection during
block report process into finer granularity. Then later I find that the work on
{{DatanodeDescriptor}} will take a lot more effort. Currently I'm not sure if
to make {{DatanodeInfo}}/{{DatanodeDescriptor}} thread safe is the best way or
necessary to achieve the final goal of HDFS-8966. Will spend more time
exploring this.

> to change DatanodeID as a follow-on work.
