Summary: S3 Gateway initializes DefaultMetricsSystem twice
Key: HDDS-8395
URL: https://issues.apache.org/jira/browse/HDDS-8395
Project: Apache Ozone
Issue Type: Improvement
Components: S3
Affects Versions: 1.3.0, 1.4.0
Reporter: okumin
I observe the following warning when I issue a request to S3 Gateway.
{code:java}
ozone-s3g-df95ff75c-4jm4c: 2023-04-07 12:49:54,343 [qtp6519275-23] WARN
impl.MetricsSystemImpl: S3Gateway metrics system already initialized! {code}
I found that's because S3 Gateway initializes DefaultMetricsSystem for erver
and client metrics.
