 CREATE VIEW followup:  derive dependencies on underlying base table 
 partitions from view definition
 ---

 Key: HIVE-1079
 URL: https://issues.apache.org/jira/browse/HIVE-1079
 Project: Hive
  Issue Type: Improvement
  Components: Query Processor
Affects Versions: 0.6.0
Reporter: John Sichi
Assignee: Prajakta Kalmegh

 When querying a view, it would be useful to know which underlying base table 
 partitions it depends on in order to know how fresh the result is (or to be 
 able to wait until all of those partitions have been loaded consistently).  
 The task is to come up with a way to perform this analysis automatically 
 (possibly overconservatively), or alternately to let the view creator 
 annotate the view definition with this dependency information, or some 
 combination of the two.
 Note that this would be useful for any complex query which directly accesses 
 base tables (not just view definitions).
