-------------------------------------
Summary: Identify Catalog HA and StateStore HA from the debug
endpoint
Key: IMPALA-12874
URL: https://issues.apache.org/jira/browse/IMPALA-12874
Project: IMPALA
Issue Type: Improvement
Components: Backend
Reporter: gaurav singh
Assignee: gaurav singh
Identify which Catalog and Statestore pod is active from the debug endpoint.
We should improve the label on catalog and statestore web ui to indicate
"Active" instance.
On the main page we could indicate "Status: Active" or "Status: Stand-by". We
could probably add the status at the top of the main page before *"Version"* .
The current details as output of a curl request on port 25020:
{code:java}
<h2>Vers<span id="v">i</span>on</h2>
<pre id="version_pre">catalogd version 4.0.0.2024.0.18.0-61 RELEASE (build

Corresponding curl request on statestored on 25010:
{code:java}
<h2>Vers<span id="v">i</span>on</h2>
<pre id="version_pre">statestored version 4.0.0.2024.0.18.0-61 RELEASE (build
82901f3f83fa4c25b318ebf825a1505d89209356)
Built on Fri Mar 1 20:13:09 UTC 2024
Build Flags: is_ndebug=true cmake_build_type=RELEASE library_link_type=STATIC
</pre>
<!-- The space after is necessary to add a space between each flag when
this page is rendered -->
<h2>Process Start Time</h2>
{code}
Catalogd active status can be figured out using the catalogd metric:
"catalog-server.active-status"
Statestored active status we probably don't have a metric so should add a
similar metric and use that to determine status.
