> Starting with Hadoop 2.6, HDFS files can be assigned to storage tiers.  Current supported
options include SSD and single copy in memory.
> It is already possible to default all temp tables to a given tier (HIVE-7313).  
> It should be possible to specify for a given table, temp table, or when they are added,
materialized views (HIVE-10459).  It should also be possible to change the storage tier for
a given table or view.
> This should be done in a way that it is not tied explicitly to HDFS (ie, other systems
may have alternate storage tiers or related concepts).
