> Environment: CDH4.5 and CDH5.0
> Reporter: Johndee Burks

> If I take a given data directories. The directories contain a data file that
> is rc format and only contains one character "1".
> {code}
> /j1/part1
> /j1/part2
> {code}
> Create the table over the directories using the following command:
> {code}
> create table j1 (a int) partitioned by (b string) stored as rcfile location
> '/j1' ;
> {code}
> I add these directories to a table for example j1 using the following
> commands:
> {code}
> alter table j1 add partition (b = 'part1') location '/j1/part1';
> alter table j1 add partition (b = 'part2') location '/j1/part2';
> {code}
> I then do the following command to the first partition:
> {code}
> alter table j1 partition (b = 'part1') concatenate;
> {code}
> Hive changes the partition location from on hdfs
> {code}
> /j1/part1
> {code}
> to
> {code}
> /j1/b=part1
> {code}
> However it does not update the partition location in the metastore and
> partition is then lost to the table. It is hard to find this out until you
> start querying your data and notice there is missing data. The table even
> still shows the partition when you do "show partitions".
