Jaewoong Jung created TAJO-1178:
-----------------------------------
Summary: Some error messages for wrong JSON queries are not so
much helpful
Key: TAJO-1178
URL: https://issues.apache.org/jira/browse/TAJO-1178
Project: Tajo
Issue Type: Bug
Reporter: Jaewoong Jung
Assignee: Jaewoong Jung
When some required fields are missing, (e.g. OpType) tsql shows a dumb error
message, "ERROR: java.lang.NullPointerException", which helps little in
figuring out the problem.
It should be more user-friendly like "Missing required filed: OpType".
