Error opening zip file or JAR manifest missing jmx_prometheus_javaagent.jar:9200:/jmx-prometheus-kafka-metrics.yaml

[nkol2307]

hi all we have an issue with .JAR file it is downloaded from this repo https://repo.maven.apache.org/maven2/io/prometheus/jmx/jmx_prometheus_javaagent/0.20.0/jmx_prometheus_javaagent-0.20.0.jar

and indead .jar file doesn't have MAIN class definition

we are starting it using
KAFKA_OPTS="-javaagent:..../jmx_prometheus_javaagent.jar=9200:...jmx-prometheus-kafka-metrics.yaml"

how is then possible to start this jar file if it doesn't contain main class

Java agents hook into the JVM via the -javagent flag and do not have a Main-Class manifest attribute.

Can you provide the full command line for the process? ps -f <PID> > output.txt

-javaagent:/usr/bin/jmx_prometheus_javaagent.jar=9200:/etc/kafka/jmx-prometheus-kafka-metrics.yaml kafka.Kafka /usr/hdp/5.0.11.8/kafka/config/server.properties this part is releveant for us not whole java command

The exporter jars are valid. Unzip correctly lists the contents and the MANIFEST.MF is correct. All integration tests pass.

This appears to be an application startup issue. Have you checked permissions on the jar and exporter YAML file related to the account running Kafka?
