["Andrew Chalfant (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-3068?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13428776#comment-13428776 ] 

Andrew Chalfant commented on HIVE-3068:
---------------------------------------

Okay, I have updated the diff to take parameterized locations and whether or not the file is deleted, so that we can test the existence of the subfolder int he export location with dfs -rmr (which throws and error if the path doesn't exist). This should resolve the issues you brought up last time.

> When a table is dropped, the contents go to the users trash but the metadata is lost. It would be super neat to be able to save the metadata as well so that tables could be trivially re-instantiated via thrift.
