[jira] [Created] (HIVE-10668) Allow users to specify storage tiers for a table

Alan Gates created HIVE-10668:
---------------------------------

             Summary: Allow users to specify storage tiers for a table
                 Key: HIVE-10668
                 URL: https://issues.apache.org/jira/browse/HIVE-10668
             Project: Hive
          Issue Type: New Feature
            Reporter: Alan Gates
            Assignee: Alan Gates


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).
