-----------------------------------
Summary: Make Decommission related configurations runtime
refreshable
Key: HDFS-15244
URL: https://issues.apache.org/jira/browse/HDFS-15244
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Ayush Saxena
Assignee: Ayush Saxena
There are certain configurations that can be tuned to increase the speed of
Decommissioning, But restarting namenode for it seems to be a heavy operation.
Propose to make these configurations, reconfigurable during runtime in order to
speed-up decommissioning as per need.
Proposed Configs :
* {{dfs.namenode.replication.work.multiplier.per.iteration}}
* {{dfs.namenode.replication.max-streams-hard-limit}}
* {{dfs.namenode.replication.max-streams}}
