Resolution: Won't Do

> Key: HDDS-5710
> URL: https://issues.apache.org/jira/browse/HDDS-5710
> Project: Apache Ozone
> Issue Type: Improvement
> Reporter: Jackson Yao
> Priority: Major
>
> in GrpcLogAppender.java, `synchronized` is used for two purposes:
> 1 protect `wait()`
> 2 protect variables like `pendingRequests`, `pending` , etc.
> i think it is better off add a separate RWLock for the second case ， and keep `synchronized` only for wait and notify, thus any slow IO option will not block notify
