-----------------------------------
Summary: The DataNode adds a log to report its progress during
addToReplicasMap execution
Key: HDFS-17446
URL: https://issues.apache.org/jira/browse/HDFS-17446
Project: Hadoop HDFS
Issue Type: Improvement
Components: hdfs
Reporter: xiaojunxiang
Attachments: image-2024-03-28-23-53-29-057.png
Datanodes do not print logs when addToReplicasMap is just started, so we will
not be aware of its progress, or even wait up to 4 hours for a large cluster.
This is very confusing.
A cluster is as follows:
