Masatake Iwasaki commented on HDFS-9895:
----------------------------------------
Current implementation does not need this because reconfiguration task (in
ReconfigurableBase) does not swap Configuration instance. Are you planning to
change the reconfiguration logic?
> Remove all cached configuration from DataNode

> Since DataNode inherits ReconfigurableBase with Configured as base class
> where configuration is maintained, all cached configurations in DataNode
> should be removed for brevity and consistency purpose.
