getMetrics

public void getMetrics(org.apache.hadoop.metrics2.MetricsCollector metricsCollector,
              boolean all)

Yes this is a get function that doesn't return anything. Thanks Hadoop for breaking all expectations of java programmers. Instead of returning anything Hadoop metrics expects getMetrics to push the metrics into the collector.

Specified by:

getMetrics in interface org.apache.hadoop.metrics2.MetricsSource

Overrides:

getMetrics in class BaseSourceImpl

Parameters:

metricsCollector - Collector to accept metrics

all - push all or only changed?
