Compatibility Issue: NoSuchMethodError with Cassandra 4.0.13

[jmachalica]

I am encountering an issue when using cassandra-exporter version 0.9.13 with Apache Cassandra 4.0.13. The exporter fails with the following error:

WARN [prometheus-netty-pool-0] 2025-02-12 18:36:47,790 DefaultChannelPipeline.java (line 1152) An exceptionCaught() event was fired, and it reached at the tail of the pipeline. It usually means the last handler in the pipeline did not handle the exception.
java.lang.NoSuchMethodError: org.apache.cassandra.locator.InetAddressAndPort.getAddress()Ljava/net/InetAddress;
	at com.zegelin.cassandra.exporter.InternalMetadataFactory.localBroadcastAddress(InternalMetadataFactory.java:90)
	at com.zegelin.cassandra.exporter.Harvester.globalLabels(Harvester.java:283)
	at com.zegelin.cassandra.exporter.netty.HttpHandler.sendMetrics(HttpHandler.java:292)

Upon further investigation, it appears that the method InetAddressAndPort.getAddress() does not exist in Cassandra 4.0.13.

• Cassandra 4.0.13: No such method in InetAddressAndPort (Javadoc)
• Cassandra 4.0.0: No such method either (Javadoc)
• Cassandra 4.1.0: The method exists, as InetAddressAndPort extends InetSocketAddress (Javadoc)

This suggests that cassandra-exporter might not be compatible with Cassandra 4.0.x.

Additionally, I noticed that there is an unmerged PR (#114) that seems to address this issue and aims to make the exporter compatible with versions <4.0, 4.1>.

Can you confirm whether cassandra-exporter 0.9.13 officially supports Cassandra 4.0.x? If not, is there a recommended workaround or fix?

Thanks in advance for your help!
