RobertIndie opened a new pull request, #23938:
URL: https://github.com/apache/pulsar/pull/23938
### Motivation
If the producer is created with some schema error, the broker will print
many error logs like this:
```
ERROR org.apache.pulsar.broker.service.ServerCnx - Try add schema failed,
remote address xxx
java.util.concurrent.CompletionException:
org.apache.pulsar.broker.service.schema.exceptions.IncompatibleSchemaException:
Producers cannot connect or send message without a schema to topics with a
schemawhen SchemaValidationEnforced is enabled
```
This error can be reported to the client and not need to print it in the
broker.

<!--
After opening this PR, the build in apache/pulsar will fail and instructions
will
be provided for opening a PR in the PR author's forked repository.
apache/pulsar pull requests should be first tested in your own fork since
the
apache/pulsar CI based on GitHub Actions has constrained resources and quota.
GitHub Actions provides separate quota for pull requests that are executed
in
a forked repository.
The tests will be run in the forked repository until all PR review comments
have
been handled, the tests pass and the PR is approved by a reviewer.
