Review comment:
Thanks @guihecheng for this work!
i have a little question, is there existing a situation that a
`datanodeDetails` is not an instance of `DatanodeInfo`, but the corresponding
datanode does have a volume that has enough space for the requirement?
if no, then every `datanodeDetails` is an instance of `DatanodeInfo`, so
can we deprecate `datanodeDetails` and only use `DatanodeInfo`?
if yes, will this lead to a misjudgegment?
