----------------------------------

             Summary: Migrate from Jaeger to OTEL tracing
                 Key: SOLR-16354
                 URL: https://issues.apache.org/jira/browse/SOLR-16354
             Project: Solr
          Issue Type: New Feature
      Security Level: Public (Default Security Level. Issues are Public)
    Affects Versions: 9.0
            Reporter: Jan Høydahl


Jaeger clients are deprecated - [https://www.jaegertracing.io/docs/1.37/client-libraries/#deprecating-jaeger-clients] and it is recommended to migrate to OTEL, see migration guide: [https://opentelemetry.io/docs/migration/opentracing/]

Plan for removing deprecated dependencies (no new functionality):
 # Deprecate jaegertracer-configurator
 # Replace jaegertracing libs with OTEL libs
 # Add a shim that converts OpenTracing traces to OpenTelemetry
 # Adapt jaegertracer-configurator so it works as it used to, while using OTEL's Jaeger exporter

Then add a new 'otel' module to Solr, with support for OTEL tracing backend, and possibly other exporters.
