Hi, I'm trying to add distributed tracing to Solr following this document: https://lucene.apache.org/solr/guide/8_6/solr-tracing.html
I downloaded the latest version, 8.6.1, and edited the ./server/solr/solr.xml file with the tracerConfig as listed in the document. I have a Jaeger backend running on my machine locally, and thus, the tracer config should be able to connect to local Jaeger backend. I run the Solr server with ./bin/solr start -d ./server -f -v But for some reason, I don't see the traces being published to Jaeger. Instead, the Solr server does not find the right Jaeger configuration and configures itself to Noop tracer. 2020-08-27 06:39:53.385 DEBUG (qtp762476028-24) [ ] o.e.j.w.WebAppContext isSystemResource==false org.apache.solr.util.tracing.GlobalTracer jar:file: ~/solr/solr-8.6.1/server/solr-webapp/webapp/WEB-INF/lib/solr-core-8.6.1.jar!/org/apache/solr/util/tracing/GlobalTracer.class 2020-08-27 06:39:53.385 DEBUG (qtp762476028-24) [ ] o.e.j.w.WebAppClassLoader WAP webapp loaded class org.apache.solr.util.tracing.GlobalTracer 2020-08-27 06:39:53.385 DEBUG (qtp762476028-24) [ ] o.e.j.w.WebAppContext isSystemResource==false io.opentracing.Tracer jar:file:~/solr/solr-8.6.1/server/solr-webapp/webapp/WEB-INF/lib/opentracing-api-0.33.0.jar!/io/opentracing/Tracer.class 2020-08-27 06:39:53.386 DEBUG (qtp762476028-24) [ ] o.e.j.w.WebAppClassLoader WAP webapp loaded interface io.opentracing.Tracer 2020-08-27 06:39:53.386 DEBUG (qtp762476028-24) [ ] o.e.j.w.WebAppContext isSystemResource==false io.opentracing.noop.NoopTracerFactory jar:file:~/solr/solr-8.6.1/server/solr-webapp/webapp/WEB-INF/lib/opentracing-noop-0.33.0.jar!/io/opentracing/noop/NoopTracerFactory.class 2020-08-27 06:39:53.386 DEBUG (qtp762476028-24) [ ] o.e.j.w.WebAppClassLoader WAP webapp loaded class io.opentracing.noop.NoopTracerFactory I'm not sure what am I doing wrong such that Solr doesn't recognize my Jaeger configuration. I am new to Solr, so I could be making a beginner mistake or a straightforward error. I did not find any other articles or similar issues reported to use for reference. I'm happy to list/publish the solution to the problem so that it helps other people if the solution calls for an improvement in docs. Any help is greatly appreciated. Thanks. a lot, Neeraj
