             Summary: Add logs in FieldValidator
                 Key: LENS-1374
                 URL: https://issues.apache.org/jira/browse/LENS-1374
             Project: Apache Lens
          Issue Type: Task
            Reporter: Rajat Khandelwal
            Assignee: Rajat Khandelwal


Exceptions of fieldValidator don't provide any info in logs and it's difficult 
to debug why fields are not queryable together.
