---------------------------------
Summary: (Umbrella) More query validation checks
Key: TAJO-571
URL: https://issues.apache.org/jira/browse/TAJO-571
Project: Tajo
Issue Type: Improvement
Components: planner/optimizer
Reporter: Hyunsik Choi
SQL is a declarative language. So, it is easy for users to submit wrong query
statements to the system. Some wrong queries are launched to a cluster even
though they are invalid and cannot be executed.
In this issue, we will add some validation checks to not allow wrong queries to
be launched to a cluster.
This is an umbrella issue. I'll create subtasks for it.
