Subject [jira] Commented: (HIVE-91) Allow external tables with different partition directory structure
Date Fri, 19 Dec 2008 12:55:44 GMT

    [ https://issues.apache.org/jira/browse/HIVE-91?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12658076#action_12658076
] 

Prasad Chakka commented on HIVE-91:
-----------------------------------

can't this be achieved by adding location (or suffix) parameter to 'create or load partition'
command. this may even exist right now. How does one define the definition (or template) of
the flexible partition naming function? a partition key might have sub-components or order
of keys could be different. This is doable but the effort required is not necessary for this
functionality.

> 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.
