Subject [jira] [Commented] (HIVE-446) Implement TRUNCATE
Date Fri, 12 Apr 2013 16:24:18 GMT

    [ https://issues.apache.org/jira/browse/HIVE-446?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13630258#comment-13630258
] 

Gang Tim Liu commented on HIVE-446:
-----------------------------------

"External table" is used in the context where data is not fully managed. If it ends up that
there is a need to remove data behind external table, a question can be asked "why do you
define it as external table?".

Saying that, possibly the proposed syntax and semantics are not consistent to "external table"
use case.

thanks
