["Johan Oskarsson (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-91?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12652074#action_12652074 ] 

Johan Oskarsson commented on HIVE-91:
-------------------------------------

Comment from Joydeep Sen Sarma on the mailinglist:
"Or we could have a 'format' spec in the create table command for how the directories are named. By default it's '%key=%value', but in this case it's '%value'. this might make it more flexible if we encounter other kinds of directory layouts."

> A lot of users have datasets in a directory structures similar to this in hdfs: /dataset/yyyy/MM/dd/<one or more files>
> Instead of loading these into Hive the normal way it would be useful to create an external table with the /dataset location and then one partition per yyyy/mm/dd. This would require the partition "naming to directory"-function to be made more flexible.
