----------------------------------
Summary: Some data is missing in the case of BROADCAST JOIN and
multi-column partition.
Key: TAJO-879
URL: https://issues.apache.org/jira/browse/TAJO-879
Project: Tajo
Issue Type: Bug
Reporter: Hyoungjun Kim
Assignee: Hyoungjun Kim
Priority: Trivial
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.
