> For Flink 1.1.1 we configured Graphite metrics settings on the flink-conf.yaml (for job manager (and taskmanager)).
> We see the following error in the log:
> 2016-08-15 14:20:34,167 ERROR org.apache.flink.runtime.metrics.MetricRegistry               - Could not instantiate metrics reportermy_reporter. Metrics might not be exposed/reported.

> We found out that this class is not packaged inside flink-dist_2.11-1.1.1.jar.
> Long story short: we had to install/provide the following jars into the lib folder to make Graphite metrics to work:
> flink-metrics-graphite-1.1.1.jar
> flink-metrics-dropwizard-1.1.1.jar
> metrics-graphite-3.1.0.jar (from dropwizard)
> We think these libraries (and the ones for Ganglia,StatsD,...) should be included in flink-dist_2.11-1.1.1.jar, for these are needed at manager startup time.
