Zhu Zhu commented on FLINK-12684:
---------------------------------

Hi [~richard.moorhead], metric reporters are session level components, thus their configurations are fixed after the session is started, and cannot be changed when submitting jobs to the session.

If you are using Flink in yarn mode rather the standalone mode, and just want to have different metric reporter configurations for different yarn sessions(they can serve different jobs), you can override flink configurations via *-D/-yD* options when starting yarn session(in session mode) or submitting job(in per job mode).

> We have a use case where we need to be able to provide job specific configuration to a metrics reporter. In other words metrics reporting needs to be done at a per job basis rather than static configuration derived from the flink installation. In general would having the ability to provide user defined config (overrides) at job submission time be a reasonable feature?
