yuruguo opened a new issue #11983: URL: https://github.com/apache/pulsar/issues/11983
**Is your enhancement request related to a problem? Please describe.** When I execute `pulsar-perf` to simulate the test, I found that the task can be started normally after some options are set to unreasonable values, but there is no instance running, which leads to a waste of resources. In fact, when these unreasonable values appear, we should check to prevent the task from starting. _**case 1:**_ `./bin/pulsar-perf consume --num-consumers -1 test` Task can be started but there is no consumption instance in subscription. **_case 2:_** `./bin/pulsar-perf produce --num-producers -1 test` Task can be started but there is no production instance. **Describe the solution you'd like** Provide a `IParameterValidator.class` for these option, perform necessary parameter checks before the task starts and exit directly after hitting. -- This is an automated message from the Apache Git Service.
