Subject [jira] [Commented] (HIVE-3068) Add ability to export table metadata as JSON on table drop
Date Sun, 05 Aug 2012 02:40:04 GMT


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.

It would be super neat to be able to save the metadata as well so that tables could be trivially
re-instantiated via thrift.
