             Summary: Reconfig slow peer parameters for datanode
                 Key: HDFS-16396
                 URL: https://issues.apache.org/jira/browse/HDFS-16396
             Project: Hadoop HDFS
          Issue Type: New Feature
            Reporter: tomscut
            Assignee: tomscut


In large clusters, rolling restart datanodes takes a long time. We can make slow peers parameters and slow disks parameters in datanode reconfigurable to facilitate cluster operation and maintenance.
