taklwu opened a new pull request, #4452:
URL: https://github.com/apache/hbase/pull/4452
tested locally and now standalone with these configuration `export
HBASE_TRACE_OPTS="-Dotel.traces.exporter=jaegar -Dotel.metrics.exporter=none"`
in `conf/hbase-env.sh` no longer failed
before the change, it's always using the default and create Otlp metrics
exporter but it cannot be done.
```
