Using multiple levels of partitions in Hive

问题

I am wondering if the following is possible. I have data in Hive partitioned by date and logger, but I also have data that does not fall under a particular logger.

e.g.

date=2012-01-01/logger=1/part000
date=2012-01-01/logger=1/part001
date=2012-01-01/logger=2/part000
date=2012-01-01/logger=2/part001
date=2012-01-01/part000

I created my table with:

create table mytable (
    ...
)
partitioned by (date string, logger int)
....
;

and added partitions:

alter table mytable add partition (date='2012-01-01', logger=1) location '/user/me/date=2012-01-01/logger=1/';
...

I can query data in the partitions, but I cannot query data in the file date=2012-01-01/part000. Is it possible to include this file without it conforming to the partitioning?

Thank you

Aaron, how did you manage to obtain such structure? Usually if partition key is missing HIVE creates partition called __HIVE_DEFAULT_PARTITION__.
