[jira] [Created] (IMPALA-8761) Configuration validation introduced in IMPALA-8559 can be improved

             Summary: Configuration validation introduced in IMPALA-8559 can be improved
                 Key: IMPALA-8761
                 URL: https://issues.apache.org/jira/browse/IMPALA-8761
             Project: IMPALA
          Issue Type: Sub-task
            Reporter: Vihang Karajgaonkar


The issue with configuration validation in IMPALA-8559 is that it validates one configuration at a time and fails as soon as there is a validation error. Since there are more than one configuration keys to validate, user may have to restart HMS again and again if there are multiple configuration changes which are needed. This is not a great user experience. A simple improvement that can be made is do all the configuration validations together and then present the results together in case of failures so that user can change all the required changes in one go.
