---------------------------------
Assignee: Andy Huang
> [Recon][UI] Containers page fetches data twice on initial load
> --------------------------------------------------------------
>
> Key: HDDS-16877
> URL: https://issues.apache.org/jira/browse/HDDS-16877
> Project: Apache Ozone
> Issue Type: Bug
> Components: Ozone Recon
> Reporter: Chi-Hsuan Huang
> Assignee: Andy Huang
> Priority: Minor
>
> When the v2 Containers page loads, the initial data requests are sent twice:
> {{/api/v1/containers/unhealthy/MISSING}},
> {{/api/v1/containers/quasiClosed?limit=0}} and {{/api/v1/clusterState}}.
> The page fetches this data in its own mount effect. {{useAutoReload}} is
> enabled by default, and it also calls {{loadContainersData}} immediately when
> it starts polling. Neither path knows about the other.
> The responses are not cached ({{NoCacheFilter}}, and both requests are in
> flight at the same time). So each page load runs the {{UNHEALTHY_CONTAINERS}}
> summary {{GROUP BY}} twice on Recon.
> The Pipelines page avoids this by setting {{initialFetch: false}} and relying
> on the first auto-reload poll. However, the Containers page still needs a
> mount fetch when auto-reload is disabled.
> Found while reviewing the tests in HDDS-9793 (#11417). Related: HDDS-14544,
> HDDS-14548, HDDS-16551. HDDS-15782 shows why simply dropping the mount fetch
> is not enough when auto-reload is off.
