Davor Bonaci commented on BEAM-2056:
------------------------------------
[~aljoscha], do you think this is first stable release-blocking? I'd say it can
possibly be deferred.
> Add tests for exporting Beam Metrics to Flink Metrics
> -----------------------------------------------------
>
> Key: BEAM-2056
> URL: https://issues.apache.org/jira/browse/BEAM-2056
> Project: Beam
> Issue Type: Improvement
> Components: runner-flink
> Reporter: Aljoscha Krettek
> Assignee: Aljoscha Krettek
> Fix For: First stable release
>
>
> There are currently no tests that verify that metrics that are reported using
> the Beam Metrics API are forwarded to Flink and a {{MetricReporter}}.
> A test for this would have to manually configure a Flink "Mini Cluster", as in
> {code}
> // start also a re-usable Flink mini cluster
> flink = new LocalFlinkMiniCluster(getFlinkConfiguration(), false);
> flink.start();
> flinkPort = flink.getLeaderRPCPort();
> {code}
> with {{getFlinkConfiguration()}}:
> {code}
> protected static Configuration getFlinkConfiguration() {
> Configuration flinkConfig = new Configuration();
> flinkConfig.setInteger(ConfigConstants.LOCAL_NUMBER_TASK_MANAGER, 1);
> flinkConfig.setInteger(ConfigConstants.TASK_MANAGER_NUM_TASK_SLOTS, 8);
> flinkConfig.setInteger(ConfigConstants.TASK_MANAGER_MEMORY_SIZE_KEY, 16);
> flinkConfig.setString(ConfigConstants.RESTART_STRATEGY_FIXED_DELAY_DELAY,
> "0 s");
> flinkConfig.setString(ConfigConstants.METRICS_REPORTERS_LIST,
> "my_reporter");
> flinkConfig.setString(ConfigConstants.METRICS_REPORTER_PREFIX +
> "my_reporter." + ConfigConstants.METRICS_REPORTER_CLASS_SUFFIX,
> MyTestReporter.class.getName());
> return flinkConfig;
> }
> {code}
> where {{MyTestReporter}} is a {{MetricReporter}} that stores metrics being
> reported to it so we can verify that they are there after the job finishes.
> Running a Pipeline on the mini cluster should be possible by specifying
> "localhost" and the port we received as a cluster endpoint.
