> Add opentracing into KMS server/client
> --------------------------------------
>
> Key: HADOOP-16286
> URL: https://issues.apache.org/jira/browse/HADOOP-16286
> Project: Hadoop Common
> Issue Type: Sub-task
> Reporter: Wei-Chiu Chuang
> Assignee: Wei-Chiu Chuang
> Priority: Major
>
> Recently, while I worked on KMS-o-meter tool, a workload replay tool for KMS,
> I added opentracing in it and in KMS server/client.(courtesy of Elek,
> Marton's tracing work in ozone, I simply took a part of it). The ability to
> understand system performance in such details is unprecedented. We were able
> to fix a system scalability bug, verify it in record time.
> File this jira to contribute the opentracing code in KMS server/client back
> to the community.
