Duo Zhang commented on HBASE-25658:
-----------------------------------
I set up a all-in-one jaeger receiver with downsampling 1.0, which means drop
all the received tracing data, to minimum the effect on the receiver side.
I modified the tracing code a bit, where I removed the tracing on
RegionScanner.next, because a scan rpc call from client side could lead to
thousands of RegionScanner.next, so it is not a good idea to trace every
RegionScanner.next call.
Still execute the same command, for HBASE-22120 with trace disabled
{noformat}

For HBASE-22120 with trace enabled and sampling ratio as 1.0, which means trace
all, the result is
{noformat}
-Dotel.traces.exporter=jaeger -Dotel.exporter.jaeger.endpoint=xxxxx:14250
-Dotel.metrics.exporter=none -Dotel.traces.sampler=parentbased_traceidratio
