    [ https://issues.apache.org/jira/browse/HDFS-9414?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15042025#comment-15042025

Xiaobing Zhou commented on HDFS-9414:
-------------------------------------

V002 patch:
1. kept all interfaces in ClientDatanodeProtocol unchanged
2. removed definition of protobuf type(e.g. request/response) to ReconfigurationProtocol.proto
3. delegated partial implementation in ClientDatanodeProtocol to ReconfigurationProtocol utilities.

The tests are covered by TestDFSAdmin not changed.

> Since reconfiguration is reused by both DataNode and NameNode, this work proposes to
refactor that part in ClientDatanodeProtocol to be reused by dedicated ReconfigurationProtocol.
