@Raufshaikh @teo123 @dimi_yu - Starting with CDP 7.1.9, Cloudera rebased ZooKeeper to version 3.8 (3.8.1.7.1.9.0-387). Beginning with ZooKeeper version 3.6.0, a new a new monitoring feature (New Metrics System ) was introduced where you can enable the Prometheus MetricsProvider [0]. By default, the Port is set to the default port number of 7000 (which is configurable by setting "metricsProvider.httpPort"). While Prometheus itself does not require the HTTP TRACE method for normal operation, this behaviour is a result of the upstream ZooKeeper implementation ZOOKEEPER-3731. We at Cloudera, actively working internally to disable HTTP TRACE in the Prometheus MetricsProvider endpoint in an upcoming CDP release as part of our continued focus on security hardening. Which will be fixed in CDP 7.3.2, released in early 2026. As a workaround for now, you can just uncheck the "Enable the Prometheus MetricsProvider" option to disable the port for Prometheus metrics.
