Marton Greber commented on KUDU-3402:
-------------------------------------
After some digging I found that Trace-viewer lives in the
[catapult-project|https://github.com/catapult-project/catapult]. It looks like
it is still maintained.
In Cloudera's catapult fork there is a [kudu
branch|https://github.com/cloudera/catapult/tree/kudu]. (it is almost 8k
commits behind :( )
> Make tracing.html work on newer browsers

> Key: KUDU-3402
> URL: https://issues.apache.org/jira/browse/KUDU-3402
> Project: Kudu
> Issue Type: Improvement
> Reporter: Marton Greber
> Priority: Minor
>
> After starting up Kudu, navigate to one of the Master or Tablet Server
> /tracing.html endpoint to see the tracing web UI. By using a recent version
> of Chrome, one gets a blank screen. Pulling up the logs, one can see the root
> cause: document.registerElement:
> {code:java}
> Uncaught TypeError: document.registerElement is not a function
> at tracing.js:31:88
> at tracing.js:31:448 {code}
> By checking the [MDN Web
> Docs|https://developer.mozilla.org/en-US/docs/Web/API/Document/registerElement],
> it can be seen, that this feature has been deprecated. In Chrome it was
> removed in version 80.
