Hi [~anu],
bq. We have trace ID on each call since the xciever client will fail if we did
not have a valid ID.
Yes, now we must pass a valid id on each call. But we didn't use a convient
way, I mean that we use {{UUID.randomUUID().toString()}} everywhere to generate
unique id. For filling this JIRA, I planned to implement a util class for
generating trace ID. By this way, if we want to make some rules for the request
id, we don't need to update it every place. But if there is already a class
implemented for this, feel free to close this, :).

> Ozone: Implement the trace ID generator

> Key: HDFS-11744
> URL: https://issues.apache.org/jira/browse/HDFS-11744
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: ozone
> Affects Versions: HDFS-7240
> Reporter: Yiqun Lin
> Assignee: Yiqun Lin
>
> Currently in ozone, if a client wants to call a container operation command,
> it requires client to create an unique id. Actually this is not a convenience
> way, we should provide a specific id generator to help us do this. Also we
> can keep the original way since sometimes the client wants to use its own
> traceID in case of error this will be help debugging and tracing.
