> 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.
