---------------------------------
Summary: When inserting empty data into a partitioned table,
existing data would be removed.
Key: TAJO-1644
URL: https://issues.apache.org/jira/browse/TAJO-1644
Project: Tajo
Issue Type: Bug
Components: query master
Reporter: Jaehwa Jung
Assignee: Jaehwa Jung
When inserting empty data into a partitioned table, existing data would be
removed. Tajo provides column value partition which is hive-style partition. In
hive, when inserting empty data into a partition, there are two cases. If you
use dynamic partitions, existing data never would be removed. But if you don't
use dynamic partitions, existing data would be removed. When inserting a data
to partition, tajo user don't specify each column and each column value. So, it
is similar to dynamic partition of hive. It seems to update deletion logic of
partitioned table.
