Arpit Agarwal commented on HDFS-9214:
-------------------------------------
Hi [~xiaobingo], the change looks good, one suggestion below.
DataXceiverServer does not need to extend ReconfigurableBase, since the
interface between DataNode and DataXceiverServer is private. Then you can
eliminate DataXceiverServer#getReconfigurableProperties and #getNewConf as no
one should be invoking these functions.
