Eui Heo created FLINK-14812:
-------------------------------
Summary: Add metric libs to Flink classpath with an environment
variable.
Key: FLINK-14812
URL: https://issues.apache.org/jira/browse/FLINK-14812
Project: Flink
Issue Type: New Feature
Components: Deployment / Kubernetes
Reporter: Eui Heo
To use the Flink metric lib you need to add it to the flink classpath. The
documentation explains to put the jar file in the lib path.
https://ci.apache.org/projects/flink/flink-docs-stable/monitoring/metrics.html#prometheus-orgapacheflinkmetricsprometheusprometheusreporter
However, to deploy metric-enabled Flinks on a kubernetes cluster, we have the
burden of creating and managing another container image. It would be more
efficient to add the classpath using environment variables inside the
constructFlinkClassPath function in the config.sh file.
