> The current registration of prometheus sink is before the initialization of s3gateway MetricsImpl.
> The symptom is the s3g prom page doesn't show detail metrics. Although the current prom page ([http://S3g:9878/prom)|http://s3g:9878/prom)] does show the metrics, it's because of the patch of HADOOP-17081. But in our production cluster, the S3g still got some performance issue, seems related to the MetricsSink's half-blocking attribute of SinkQueue.
> This ticket is to fix this issue.
