Xiaoyu Yao commented on HDDS-4648:
----------------------------------
When the DN leader append logs to the followers, if the statemachine data is
evicted and need to issue a ReadChunk for WriteChunk request. The ReadChunk
should populate the block token from the original WriteChunk request.
Otherwise, we will see errors like:

ratis.ContainerStateMachine: gid group-FBDA8669767C :
