> If the data directory is the following, some data is missing.
> {noformat}
> /tajo/warehouse/table1/year=2014/month=01/hour=12/part-01-00000
> /tajo/warehouse/table1/year=2014/month=02/hour=12/part-01-00000
> {noformat}
> SeqScanExec uses a last partition column path's name as a broadcast table's
> cache key.
> In this case the table is partitioned by year, month, hour. So the cache key
> is "hour=12" which is not unique.
> It should be fixed.
