Work Description: elek commented on pull request #16: HDDS-2297. Enable
Opentracing for new Freon tests
URL: https://github.com/apache/hadoop-ozone/pull/16
## What changes were proposed in this pull request?
HDDS-2022 introduced new freon tests, but the initial root span of
opentracing is not created before the test execution. We need to enable
opentracing to get better view about the executions of the new freon test.
## What is the link to the Apache JIRA
https://issues.apache.org/jira/browse/HDDS-2297
## How this patch can be tested?
Start an ozoneperf cluster:
```
cd hadoop-ozone/dist/target/ozone-0.5.0-SNAPSHOT/compose/ozoneperf/
docker-compose up -d --scale datanode=3
```
If HDDS-2296 is not yet merged, stop old-style freon:
```
docker-compose stop freon
```
Start new freon test:
```
docker-compose exec scm bash
ozone freon ockg -n 10
```
Open the jaeger web ui: http://localhost:16686/
Choose _freon_ under the service and click to the _search_.
On the right side you should see results with the name _freon:
OzoneClientKeyGenerator_ and with multiple sub-spans.
Without the patch you can see entries with strange name (...span without
root...)
