Describe the bug
Discovery stats structure got updated in #10670
This is causing org.opensearch.backwards.MixedClusterClientYamlTestSuiteIT.test {p0=nodes.stats/30_discovery/Discovery stats} tests to fail

https://build.ci.opensearch.org/job/gradle-check/28987/

@amkhar can you please take a look and update the test asap.

Also check if other node stats test failures are related

org.opensearch.backwards.MixedClusterClientYamlTestSuiteIT.test {p0=nodes.stats/20_response_filtering/Nodes Stats with response filtering}

I'll take a look shortly. Thanks for reporting this.

These mixed cluster test were failing even before https://build.ci.opensearch.org/job/gradle-check/28795/testReport/junit/org.opensearch.b[…]iteIT/test__p0_nodes_stats_30_discovery_Discovery_stats_/
GC link : https://build.ci.opensearch.org/job/gradle-check/28795/
Also I checked the code specifically for discovery one

- do:
      nodes.stats:
        filter_path: "nodes.*.discovery"

  - is_false: cluster_name
  - is_true:  nodes
  - is_false: nodes.$master.name
  - is_false: nodes.$master.jvm
  - is_true:  nodes.$master.discovery

I did this from code base.

curl localhost:9200/_nodes/stats?filter_path=nodes.*.discovery
{"nodes":{"Ubn8Zxo9R06G299on2XfCw":{"discovery":{"cluster_state_queue":{"total":0,"pending":0,"committed":0},"published_cluster_states":{"full_states":2,"incompatible_diffs":0,"compatible_diffs":0},"cluster_state_stats":{"overall":{"update_count":2,"total_time_in_millis":101,"failed_count":0}}}}}}

We’ll always get discovery section as nothing is changed in that.

After rebasing from main these failures will be gone as new version which is merged in main is 2.12.0
Please close this issue once you verify that other PRs are not facing this after merging from main.
