Question about INSERT INTO for external table

Hi, All,

In my experience, Tajo supports Hive External Tables in a READ-ONLY manner.

I mean Tajo reads from external table well, but INSERT INTO and INSERT
OVERWRITE INTO does not generate sub folder structure of EXTERNAL TABLE
properly.

Is it possible to improve in order to support EXTERNAL TABLE in a
READ-WRITE mode?

Best regards,
Dongjoon.

Since Tajo documents says,

Compatibility Issues with Apache Hive™
  If partitioned tables of Hive are created as external tables in Tajo,
Tajo can process the Hive partitioned tables directly.   There haven’t
known compatibility issues yet.

I will make an issue for this.

Best regards,
Dongjoon.
