----------------------------------
Summary: Adding logging to print the sorted datanodes list for
topology aware read
Key: HDDS-11381
URL: https://issues.apache.org/jira/browse/HDDS-11381
Project: Apache Ozone
Issue Type: Bug
Reporter: Varsha Ravi
Assignee: Varsha Ravi
{*}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.
