Subject [jira] Commented: (HIVE-972) support views
Date Wed, 23 Dec 2009 01:47:31 GMT

    [ https://issues.apache.org/jira/browse/HIVE-972?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12793882#action_12793882

Prasad Chakka commented on HIVE-972:

mainly i don't understand how 'show partitions' will work on views, or whether it should work
at all. if it is not supported then following issues will make it difficult to use views

* 'show partitions' is a very useful function for downstream processes that are waiting on
availability on a particular partition. 
* Partition keys are also useful metadata information for users browsing views
* In a 'strict' mode where a predicate on a partition key is required for any partitioned
table, a user has to know what column the predicate should be applied which then will be translated
to base tables' partition columns.
