Subject [jira] [Created] (HADOOP-16286) Add opentracing into KMS server/client
Date Thu, 02 May 2019 00:58:00 GMT
Wei-Chiu Chuang created HADOOP-16286:

             Summary: 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

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.
