Chesnay Schepler commented on FLINK-13406: ------------------------------------------ I'm not sure; it will never affect users running against actual clusters; it's just a gotcha that exists in tests. > MetricConfig.getInteger() always returns null > --------------------------------------------- > > Key: FLINK-13406 > URL: https://issues.apache.org/jira/browse/FLINK-13406 > Project: Flink > Issue Type: Bug > Components: Runtime / Metrics > Affects Versions: 1.6.3 > Reporter: Ori Popowski > Priority: Major > > {{MetricConfig}}'s {{getInteger}} will always return the default value. > The reason is, since it delegates to Java's {{Properties.getProperty}} which > returns null if the type of the value is not {{String}}. > h3. Reproduce > # Create a class {{MyReporter}} implementing {{MetricReporter}} > # Implment the {{open()}} method so that you do {{config.getInteger("foo", > null)}} > # Start an {{ExecutionEnvironment}} with and give it the following > Configuration object: > {code:java} > configuration.setString("metrics.reporters", "my"); > configuration.setClass("metrics.reporter.my.class", MyReporter.class) > configuration.setInteger("metrics.reporter.my.foo", 42);{code} > # In {{open()}} the value of {{foo}} is null. -- This message was sent by Atlassian JIRA (v7.6.14#76016)
