>
> HTableDescriptor's compareTo function compares a set of HColumnDescriptors
> against another set of HColumnDescriptors. It iterates through both, relying
> on the fact that they will be in the same order.
> In my testing, I may have seen this issue come up, so I decided to fix it.
> It's a straightforward fix. I convert the sets into a hashset for O(1)
> lookups (at least in theory), then I check that all items in the first set
> are found in the second.
> Since the sizes are the same, we know that if all elements showed up in the
> second set, then they must be equal.
