----------------------------------------
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.
