> Allow block replication parameters to be refreshable
> ----------------------------------------------------
>
> Key: HDFS-14560
> URL: https://issues.apache.org/jira/browse/HDFS-14560
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: namenode
> Affects Versions: 3.3.0
> Reporter: Stephen O'Donnell
> Assignee: Stephen O'Donnell
> Priority: Major
> Attachments: HDFS-14560.001.patch
>
>
> There are 3 key parameters that control the speed of block replication across
> the cluster:
> {code}
> dfs.namenode.replication.max-streams
> dfs.namenode.replication.max-streams-hard-limit
> dfs.namenode.replication.work.multiplier.per.iteration
> {code}
> These are used when decomissioning nodes and when under replicated blocks are
> being recovered across the cluster. There are times when it may be desirable
> to increase the speed of replication and then reduce it again (eg during off
> peak hours) without restarting the namenode.
> Therefore it would be good to be able to reconfigure / refresh these
> parameters dynamically without a namenode restart.
> This Jira is to allow these parameters to be refreshed at runtime without a
> restart.
