Johan Oskarsson commented on HIVE-126:
--------------------------------------
Sure I'll update the HIVE-142 after Christmas, there is already a half working
example patch if you want to have a look. It's worth noting that the HIVE-142
will require this patch to work.
> Don't fetch information on Partitions from HDFS instead of MetaStore

> Key: HIVE-126
> URL: https://issues.apache.org/jira/browse/HIVE-126
> Project: Hadoop Hive
> Issue Type: Improvement
> Components: Metastore
> Reporter: Johan Oskarsson
> Assignee: Johan Oskarsson
> Fix For: 0.2.0
>
> Attachments: HIVE-126.patch, HIVE-126.patch

> When investigating HIVE-91 an issue came up where the information on what
> partitions a table contains is loaded by listing the directories in the table
> directory on HDFS. This is then used to overrule what is in the MetaStore if
> any difference is found.
> * Would it not be preferable if MetaStore is the one authority on what the
> table contains?
> * It will also be a major hassle (or impossible?) to retrieve this
> information from HDFS with external tables that have non standard partition
> names (HIVE-91), such as: table/2008/01/08/portugal where "2008/01/08" is one
> partition value and "portugal" is another.
