------------------------------------
that code was needed when we have both the old and new code bases were
operating against the same data at the same time. but no longer needed can be
safely removed.

> 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

> 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.
