Allen Wittenauer commented on HDFS-6808:
----------------------------------------
A quick vote around the office came out to be about a 5:1 ratio, with most
agreeing that refresh and reconfig are essentially the same operation.
That said, we can eventually make refresh point to reconfig after enough users
complain about it. So I'll go +0.
> Add command line option to ask DataNode reload configuration.

> The workflow of dynamically changing data volumes on DataNode is
> # Users manually changed {{dfs.datanode.data.dir}} in the configuration file
> # User use command line to notify DN to reload configuration and updates its
> volumes.
> This work adds command line support to notify DN to reload configuration.
