Anoop Sam John updated HBASE-24102: ----------------------------------- Description: When using RegionMover tool to unload the regions from a given RS, it decides the list of destination RSs by {code} List<ServerName> regionServers = new ArrayList<>(); regionServers.addAll(admin.getRegionServers()); // Remove the host Region server from target Region Servers list ServerName server = stripServer(regionServers, hostname, port); ..... // Remove RS present in the exclude file stripExcludes(regionServers); stripMaster(regionServers); {code} Ya it is removing the RSs mentioned in the exclude file. Better when the RegionMover user is NOT mentioning any exclude list, we can exclude the draining/decommissioning RSs Admin#listDecommissionedRegionServers() was: When using RegionMover tool to unload the regions from a given RS, it decides the list of destination RSs by {code} List<ServerName> regionServers = new ArrayList<>(); regionServers.addAll(admin.getRegionServers()); // Remove the host Region server from target Region Servers list ServerName server = stripServer(regionServers, hostname, port); ..... // Remove RS present in the exclude file stripExcludes(regionServers); stripMaster(regionServers); {code} Ya it is removing the RSs mentioned in the exclude file.
