Description

Context: The sortDatanodes method in the KeyManagerImpl class used to include logging to print the sorted list of datanodes for topology-aware reads. However, as part of the changes introduced in HDDS-9343, which moved the sortDatanodes logic to the OM (Ozone Manager), this logging was removed.

Action Required: To reinstate this functionality, add logging to the sortByDistanceCost method—called from the KeyManagerImpl class—to print the sorted list of datanodes. This will help maintain visibility into the datanode sorting process in the new implementation.
