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. -- This message was sent by Atlassian Jira (v8.20.10#820010)
