bq. Your recent tweet about this before giving me a chance to respond is
unfortunate, especially given that HDFS-4672 is overlapping with HDFS-2832. -
isn't this the pot calling the kettle black?
This argumentation rather than hearing those concerns, the scope increase here
in the first place that ignored HDFS-4672 - and now in addition it is a
"duplicate", and the unanswered private communication all indicate that there
is some kind of competitive dynamic here that is not helpful. I prefer to
defuse the situation and move on rather than engage in some kind of debate club
atmosphere. Therefore today I resolved HDFS-4672 as Later. Please see my
comment at the tail of it.

> HDFS currently supports configuration where storages are a list of
> directories. Typically each of these directories correspond to a volume with
> its own file system. All these directories are homogeneous and therefore
> identified as a single storage at the namenode. I propose, change to the
> current model where Datanode * is a * storage, to Datanode * is a collection
> * of strorages.
