Joydeep Sen Sarma commented on HIVE-126:
----------------------------------------
+1. looks good.
let me take a look at hive-142 as well - it would be better if we can get them
both in at the same time ..
> 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
> Affects Versions: 0.19.0
> Reporter: Johan Oskarsson
> Assignee: Johan Oskarsson
> Fix For: 0.19.0
>
> 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.
