CREATE VIEW followup:  track view dependency information in metastore
---------------------------------------------------------------------

                 Key: HIVE-1073
                 URL: https://issues.apache.org/jira/browse/HIVE-1073
             Project: Hadoop Hive
          Issue Type: Improvement
          Components: Metastore
    Affects Versions: 0.6.0
            Reporter: John Sichi
            Assignee: John Sichi
             Fix For: 0.6.0


Add a generic mechanism for recording the fact that one object depends on another.  First
use case (to be implemented as part of this task) would be views depending on tables or other
views, but in the future we can also use this for views depending on persistent functions,
functions depending on other functions, etc.

This involves metastore modeling, QL analysis for deriving and recording the dependencies
(Ashish says something may already be available from the lineage work), and CLI support for
browsing dependencies.
