      Description

      If the data directory is the following, some data is missing.

      /tajo/warehouse/table1/year=2014/month=01/hour=12/part-01-00000
      /tajo/warehouse/table1/year=2014/month=02/hour=12/part-01-00000
      

      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.
