> [UnloadRegions log message|[https://github.com/apache/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/util/RegionMover.java#L649-L650]] uses the hostname to show where regions are unloading from. When a host runs multiple region servers, the hostname in the log message alone is insufficient to identify which specific region server is unloading regions.
> The proposed change is to use ServerName in the log, making it easier to distinguish between region servers on the same host similar to [loadRegions log message|https://github.com/apache/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/util/RegionMover.java#L366-L367].
> Here are two sample log messages, one from unload regions and the other from load regions
> Unload regions
> 2025-11-20 10:53:31.322 [pool-7-thread-1] INFO o.a.hadoop.hbase.util.RegionMover:472 - Moving 322 regions from host1.xyz.com to 2 servers using 10 threads .Ack Mode: true
> Load regions
> 2025-11-20 10:54:59.690 [pool-13-thread-1] INFO o.a.hadoop.hbase.util.RegionMover:330 - Moving 322 regions to thost1.xyz.com,16023,1763654092964 using 10 threads.Ack mode:true
