See the output of bake to retrieve the image tag for <image-tagged-with-the-major-version>.

I ran the current smoke test (from main) on this image 3 times, the /stackable/phoenix/bin/psql.py /stackable/phoenix/examples/WEB_STAT.sql /stackable/phoenix/examples/WEB_STAT.csv /stackable/phoenix/examples/WEB_STAT_QUERIES.sql did hang up every time.
This is the same issue we had with HBase 2.5 :(

On vacation and all comments have been addressed
