[jira] [Created] (ASTERIXDB-1253) A warning can be printed if a user-provided hint is not applied.

Taewoo Kim created ASTERIXDB-1253:
-------------------------------------

             Summary: A warning can be printed if a user-provided hint is not applied.
                 Key: ASTERIXDB-1253
                 URL: https://issues.apache.org/jira/browse/ASTERIXDB-1253
             Project: Apache AsterixDB
          Issue Type: Improvement
            Reporter: Taewoo Kim


When a user provides a certain hint (e.g., index_nl), a user expects that the given hint will be applied. If somehow the optimizer decides that the given hint is not applicable, we can print out a message that the hint was disabled during the execution of a query. Maybe we can return this warning along with the result. So, a client can print out this message.
