<p>A bit unclear sentence <a href="https://kubernetes.io/docs/concepts/workloads/controllers/job/#completion-mode" rel="nofollow noreferrer">in the doco</a>:</p>
<blockquote>
<p>Note that, although rare, more than one Pod could be started for the same index, but only one of them will count towards the completion count.</p>
</blockquote>
<p>So say it happens, there are two pods in an Indexed job with the same index.
Now, one of them is failed (the <code>restartPolicy = &quot;Never&quot;</code>), another succeed. Assume that all other pods succeed. Will the job fail overall? Or maybe it depends on which one of those sharing the same index was first - the succeeded or the failed one? Or is it totally indeterminate?</p>

<p>The first sentence is important:</p>
<blockquote>
<p>The Job is considered complete when there is one successfully completed Pod <strong>for each index</strong>.</p>
</blockquote>
<p>There can be duplicated index but for each index, only <strong>one</strong> (the one that reached Completed first) will be counted for <code>spec.completions</code>.</p>
