> Replace HTrace with OpenTelemetry
> ---------------------------------
>
> Key: HBASE-22120
> URL: https://issues.apache.org/jira/browse/HBASE-22120
> Project: HBase
> Issue Type: New Feature
> Components: tracing
> Affects Versions: 3.0.0-alpha-1
> Reporter: Sergey Shelukhin
> Assignee: Duo Zhang
> Priority: Major
> Fix For: 3.0.0-alpha-1
>
>
> h2. Deprecate HTrace usage in HBase
> * HBase 1.x (branch-1)
> * Declare HTrace (htrace 3.x) deprecated in the user doc.
> * HBase 2.x (branch-2)
> * Declare HTrace deprecated in the user doc. Furthermore, state that it is
> known not working.
> * Either fix the trace context propagation bug in HBase 2.x, or backport
> OpenTracing support from the master branch. I am inclined to the latter.
> * HBase 3.x (master branch)
> * Remove HTrace entirely.
> * Add OpenTracing APIs. Potentially backport to HBase 2.4.
> * Replace OpenTracing API with OpenTelemetry when the latter stabilizes.
> h1. Milestones
> # Doc -- deprecation notice
> # Replace existing HTrace code with OpenTracing code in the master branch
> (3.x)
> # Java (a [poc|https://github.com/jojochuang/hbase/tree/HBASE-22120] is
> currently under way)
> # HBase shell and scripts (Ruby, shell script)
> # Doc
> # Add new trace instrumentation code for new features not instrumented by
> the existing HTace code.
> # Propagate the traces to other systems such as HDFS and MapReduce.
> # Support other OpenTracing tracers.
> ======== Update ========
> As OpenTracing has now been replaced by OpenTelemetry, the goal finally
> becomes replacing HTrace with OpenTelemetry.
