Suresh Srinivas commented on HDFS-2832:
---------------------------------------
I have created couple of jiras, thus dumping out stuff I have been carrying in
my head (and other that I have discussed this with) for a long time. These set
of jiras enable support for heterogeneous storages in different tiers. I would
like to start working on HDFS-4985 immediately as this might also be useful for
expressing datanode cache in HDFS-4949 in a way that is compatible with the
proposal here.

> 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.
