Duo Zhang commented on HBASE-25373:
-----------------------------------
After learning the docs of open-telemetry-java and
opentelemetry-java-instrumentation, I think for a modern style tracing
framework for java, the typical way is to support tracing through a java agent,
without touching the code, and all the related configs for tracing, will be
passed in through command line when starting. Anyway, I think the basic rule
here, is to minimize the modification on java code.
For HBase, I do not know whether it is easy to implement an agent and push it
into open telemetry. It is not designed for better tracing, so let's try to use
the opentelemetry-api to manually add tracing support first. Later we could see
if it is possible to use an agent to do the instrumentation automatically. And
also, I think we should remove all the sampler related code, as it will pull in
the dependency of sdk and exporter.
Will update the PR soon.
