Jihoon Son commented on TAJO-266:
---------------------------------
For this issue, I created a new branch called 'DAG-execplan-branch'.
I'll proceed tests for this issue in this branch as mentioned above.
Also, a new version of the same name is created in Jira.
All the issues about this branch should include DAG-execplan-branch in its fix
versions.
