Hello @Pedro Heleno Isolani​ ,

my temporary workaround is manually install missing libs/jars:

io.netty:netty-transport-native-kqueue:4.1.59.Final

io.netty:netty-resolver-dns-native-macos:4.1.59.Final

io.netty:netty-transport-native-epoll:4.1.59.Final.

The main reason for the error is that during installation of kusto-spark-lib the "netty*" jars are downloaded with different file names:

netty-transport-native-kqueue-4.1.59.Final-osx-x86_64.jar
