+## Updated Configuration with Newer Versions of OpenTelemetry
+
+The original tracing example above was written for Accumulo 2.1.0 which uses
OpenTelemetry 1.19.0. Accumulo 2.1.4 has been updated to use OpenTelemetry
1.48.0, which requires different configuration. When working with Accumulo
2.1.4 or any deployment using OpenTelemetry 1.48.0 or newer, use OTLP
(OpenTelemetry Protocol) instead of the direct Jaeger exporter.
+
+Follow steps 1–4 from the [Tracing Example](#tracing-example) section, then
use these updated steps in place of steps 5-6:
+
+1. Configure the OpenTelemetry JavaAgent in accumulo-env.sh with OTLP export:
+ ```bash
+ JAVA_OPTS=('-Dotel.traces.exporter=otlp'
'-Dotel.exporter.otlp.endpoint=http://localhost:4317'
'-Dotel.metrics.exporter=none' '-Dotel.logs.exporter=none' "${JAVA_OPTS[@]}")
+ JAVA_OPTS=('-javaagent:path/to/opentelemetry-javaagent.jar'
"${JAVA_OPTS[@]}")
+ ```
+2. Start Jaeger with OTLP support:
+ ```bash
+ docker run --rm --name jaeger \
+ -p 16686:16686 \
+ -p 4317:4317 \
+ -p 4318:4318 \
+ -p 5778:5778 \
+ -p 9411:9411 \
+ jaegertracing/jaeger:2.3.0
+ ```
+
+After completing these updated steps, continue with steps 7-8 from the
original instructions to view traces in Jaeger.
