> The HBase, JobManager and TaskManager containers all start. It failed the
> same way on the push of e0d1e58932 and on all nine weeklies from 2026-07-19
> to 2026-09-27 in which the main cell got to the test (2026-08-02 and
> 2026-09-06 were cancelled by the v4.0 cell). The last green weekly was
> 2026-05-24, still on 2.6.4. Since 2026-10-04 the test fails earlier, in the
> HBase image build.
