Subject [jira] [Commented] (HIVE-3470) Add archived tables as input entity for select statement
Date Mon, 17 Sep 2012 03:53:07 GMT

    [ https://issues.apache.org/jira/browse/HIVE-3470?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13456745#comment-13456745

Namit Jain commented on HIVE-3470:
----------------------------------

One of the problems with adding Table as an input is that all DDL operations on the table
would block.
For eg:

alter table set tblProperties etc.

would block while someone is selecting from any partition.

> The table is not passed as ReadEntity. So when prehooks check the ReadEntities, an arhived
table is not detected. This is for task:
