[jira] [Created] (IMPALA-13866) Add the timestamp in /jvm-threadz page

Quanlong Huang created IMPALA-13866:
---------------------------------------

             Summary: Add the timestamp in /jvm-threadz page
                 Key: IMPALA-13866
                 URL: https://issues.apache.org/jira/browse/IMPALA-13866
             Project: IMPALA
          Issue Type: Improvement
            Reporter: Quanlong Huang


In the WebUI, /jvm-threadz page shows the stacktrace of JVM threads similar to jstack output. This is useful for env where jstack is missing. Comparing to the jstack output, the timestamp of taking these stacktraces is missing in the page. We should add it to help comparing stacktraces of different snapshots.

Here is where we handler the request:
https://github.com/apache/impala/blob/356b7e5ddf7868968fb76ca55a8046d0291388fd/be/src/util/thread.cc#L427

and the web template:
