I think the question for this ticket is independent of metrics and Kubernetes. The general question is whether we want to add an Hadoop-independent environment variable such as {{CLASSPATH_ADDITIONAL_JARS}} that we document and commit to maintain for our start up scripts. Personally, I would find this beneficial in the standalone job use case. [~plucas] What do you think? --- I'm not sure who in the Flink community has good insight on the scripts and can help us make a decision here.

It would be more > efficient to add the classpath using environment variables inside the > constructFlinkClassPath function in the config.sh file. -- This message was sent by Atlassian Jira (v8.3.4#803005)
