> Key: HDFS-17901

> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs
> Affects Versions: 3.4.3
> Reporter: yue.wang
> Assignee: Yue Wang
> Priority: Major
> Labels: pull-request-available
>
> In DFSNetworkTopology#getEligibleChildren(), when iterating over
> excludedNodes, the method only handles DatanodeDescriptor and
> DFSTopologyNodeImpl types but misses the DatanodeInfo type. This causes
> storageCount to be incorrectly calculated (overestimated), leading to
> inconsistency with the parent method chooseRandomWithStorageType() and
> potentially incorrect weighted random node selection.
