## Proposed changes When executing routine load job, there may encounter StackOverflowException. This is because the expr in column setting list will be analyze for each routine load sub task, and there is a self-reference bug that may cause endless loop when analyzing expr. The following columns expr list may trigger this bug: ``` columns(col1, col2, col2=null_or_empty(col2), col1=null_or_empty(col2)) ``` This fix is verified by user, but I can't add regression test for this case, because I can't submit a routine load job in our regression test, and this bug can only be triggered in routine load. ## Further comments If this is a relatively large or complex change, kick off the discussion at [[email protected]](mailto:[email protected]) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
