------------------------------------
Summary: 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
{{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.
