KAFKA-2455: Test Failure: kafka.consumer.MetricsTest > testMetricsLeak
@guozhangwang
I reproduced this;
Every time this test failed, I found extra "type=DelayedFetchMetrics,
name=ExpiresperSec, fetcherType=consumer/follower" inside
Metrics.defaultRegistry().allMetrics().keySet();
that is because for "DelayedFetch", object DelayedFetchMetrics are loaded
dynamically in function "onExpiration";
To fix, I explicitly load this object;
Is it appropriate?
