Description

This task/issue was being discussed in the vote of HBASE-25853

I've not seen anyone report their success at integrating these changes into a telemetry system and showing end-to-end tracing of a service call. As I recall from the last 2.5 discuss thread, we wanted this to be the banner feature for the minor release. Since we don't have this end-to-end confirmation, do we have someone who's volunteered to demonstrate that final proof-of-integration in a timely manner? Perhaps that someone is keen to be release manager for 2.5.

What a `service call` mean ? (pending discussion on above email exchange or on this JIRA)
e.g. for RPCclient/AbstractRpcClient, it trace at the AbstractRpcClient#callMethod level with a span of `RpcClient.callMethod` . or whenever a connection is closed, it will emit `AsyncConnection.close`
