### Search before asking - [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar. ### Motivation When running on a Java client on Mac M1 we receive the annoying `WARN` log statement: > 22:07:00.494 [Test worker] WARN org.apache.pulsar.shade.io.netty.resolver.dns.DnsServerAddressStreamProviders - Can not find org.apache.pulsar.shade.io.netty.resolver.dns.macos.MacOSDnsServerAddressStreamProvider in the classpath, fallback to system defaults. This may result in incorrect DNS resolutions on MacOS. This can lead to actual issues - but in most cases is just an annoyance. The suggested workaround is to add the M1-specific dependency [netty-resolver-dns-native-macos]( https://mvnrepository.com/artifact/io.netty/netty-resolver-dns-native-macos/4.1.85.Final) when running on M1 ([example](https://github.com/netty/netty/issues/11020#issuecomment-1193280582)). This does not work for Pulsar when using the `pulsar-client-all` shared jar because it attempts to load the M1 version w/ the shaded prefix (`org.apache.pulsar.shade.io.netty.resolver.dns.macos.MacOSDnsServerAddressStreamProvider` rather than `io.netty.resolver.dns.macos.MacOSDnsServerAddressStreamProvider`). From `DnsServerAddressStreamProviders.java` in `pulsar-client-all:2.10.2` ```java package org.apache.pulsar.shade.io.netty.resolver.dns; ... public final class DnsServerAddressStreamProviders { static { Constructor<? extends DnsServerAddressStreamProvider> constructor = null; if (PlatformDependent.isOsx()) { try { Object maybeProvider = AccessController.doPrivileged(new PrivilegedAction<Object>() { public Object run() { try { return Class.forName("org.apache.pulsar.shade.io.netty.resolver.dns.macos.MacOSDnsServerAddressStreamProvider", true, DnsServerAddressStreamProviders.class.getClassLoader()); } catch (Throwable var2) { return var2; } } }); ``` ### Solution A couple of possible solutions: 1. Provide a pulsar artifact that comes w/ the shaded M1 lib 2. Provide instructions for users to shade the lib themselves in both Gradle and Maven ### Alternatives _No response_ ### Anything else? _No response_ ### Are you willing to submit a PR? - [X] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
