What kind of beans were they?
If they are string beans then you should pick them before the pods fill and you can feel the beans. If the beans are hard then depending on the kind of bean you can use them as dry beans.
Example black eye peas, pods can be eaten whole when it is young like string beans or shelled and used as dry beans later.
If what you have is a shelling bean like lima or Italian beans, I have never tried eating them in the pod.
If you cooked them for an hour, I'm thinking they were very old.
Happy gardening in Hawaii. Gardens are where people grow.
