Riza Suminto created IMPALA-12482:
-------------------------------------
Summary: StatestoreSubscriber.UpdateState logging is too noisy at
VLOG level 2
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.
