Hi [~babokim]
Thank you for your contribution.
You patch looks good, and I just updated
TestJoinBroadcast::testBroadcastMultiColumnPartitionTable as follows:
- remove unnecessary comments
- Adding result file data
I'll commit it to master branch now.
Cheers

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

> /tajo/warehouse/table1/year=2014/month=01/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.
