> Key: IMPALA-12482
> URL: https://issues.apache.org/jira/browse/IMPALA-12482
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend
> Affects Versions: Impala 4.3.0
> Reporter: Riza Suminto

> StatestoreSubscriber.UpdateState is a periodic RPC that happens every 1 second. This RPC is wrapped with RpcEventHandler (rpc-trace.cc) which has VLOG_RPC (or VLOG(2)) in it.
> Debugging Impalad by lowering VLOG level from 1 to 2 has been difficult due to noise from this StatestoreSubscriber.UpdateState RPC. Following lines will be printed to Impalad logs, burying other log lines that is actually more important:
> {code:java}
> I0926 15:54:15.255978 829 rpc-trace.cc:256] RPC call: statestore-subscriber:StatestoreSubscriber.UpdateState from 127.0.0.6:41953 took 123.000us
> I0926 15:54:15.356801 848 rpc-trace.cc:236] RPC call: StatestoreSubscriber.UpdateState(from 127.0.0.6:35361) {code}
> RpcEventHandler should be modified to allow different VLOG level for different RPC handler.
