Stefan Miklosovic commented on CASSANDRA-14667:
-----------------------------------------------
Ahaa I know what is going on ... the Java driver we use for tests itself uses
Dropwizard of a different version we just stopped to use and imports are
different suddenly.
driver we are using, of version 3.11.0, uses
<metrics.version>3.2.2</metrics.version> in
https://central.sonatype.com/artifact/com.datastax.cassandra/cassandra-driver-parent/3.11.0
This parent
https://central.sonatype.com/artifact/com.datastax.oss/java-driver-parent/4.15.0
uses metrics <metrics.version>4.1.18</metrics.version>
However, what we could do is to do this:
{code}
try (com.datastax.driver.core.Cluster c =
com.datastax.driver.core.Cluster.builder()
.withoutMetrics()
.addContactPoint("127.0.0.1").build();
{code}
Do you see that ".withoutMetrics()" method? Once there, the test passes (e.g.
tests extending AbstractNetstatsStreaming, modified populateData and
changeReplicationFactor methods).
So, we either put this "withoutMetrics()" everywhere where we are building
Cluster, or we update the project to use Cassandra driver 4 (that is pretty
challenging!)
I am not completely sure if we use these "metrics" via driver, I do not think
so but should be double checked. I think that for the sake of tests we do not
need them at all.

> Cassandra currently uses Metrics 3.1.5. Version 4.0.0 added some fixes for
> Java 9 compatibility. It would be good to upgrade the Metrics library as part
> of the version of Cassandra that adds Java 9 compatibility
> (https://issues.apache.org/jira/browse/CASSANDRA-9608).
