I have the same problem with a slightly different version of the connector (change on the minor version). I have a job that runs every hour and specifically, this started to happen on the 23rd of January onwards. The error indeed does say the same:

Run result unavailable: job failed with error message
 Library installation failed for library due to user error for maven {
  coordinates: "com.microsoft.azure.kusto:kusto-spark_3.0_2.12:3.1.6"
}
. Error messages:
Library installation attempted on the driver node of cluster 0123-210011-798kk68l and failed. Please refer to the following error message to fix the library or contact Databricks support. Error Code: DRIVER_LIBRARY_INSTALLATION_FAILURE. Error Message: java.util.concurrent.ExecutionException: java.io.FileNotFoundException: File file:/local_disk0/tmp/clusterWideResolutionDir/maven/ivy/jars/io.netty_netty-transport-native-kqueue-4.1.59.Final.jar does not exist

I've tried installing "io.netty:netty-transport-native-kqueue:4.1.59.Final" from maven and it worked. However, when installing "com.microsoft.azure.kusto:kusto-spark_3.0_2.12:3.1.6" it shows the following error, pointing to a different jar file:

Library installation attempted on the driver node of cluster 0131-110547-yen1qo6z and failed. Please refer to the following error message to fix the library or contact Databricks support. Error Code: DRIVER_LIBRARY_INSTALLATION_FAILURE. Error Message: java.util.concurrent.ExecutionException: java.io.FileNotFoundException: File file:/local_disk0/tmp/clusterWideResolutionDir/maven/ivy/jars/io.netty_netty-resolver-dns-native-macos-4.1.59.Final.jar does not exist

Also, I can confirm that other libraries can be installed via maven, e.g., "com.databricks:databricks-jdbc:2.6.32" (see screenshot below)
