**Describe the problem you faced**
I recently enabled metrics reporting from Hudi via Cloudwatch. When I did
that, the job completes successfully but no metrics are published and in the
logs I see the following error:
```
25/03/27 23:07:34 INFO CloudWatchReporter: Reporting Metrics to CloudWatch.
25/03/27 23:07:34 ERROR ScheduledReporter: Exception thrown from
CloudWatchReporter#report. Exception was suppressed.
