[GitHub] [arrow-datafusion] andygrove commented on issue #2877: hash_join panics ('called `Option::unwrap()` on a `None` value)

   I think the issue is that we don't have type coercion for join keys so joining a number column to a string can cause this. in `fn equal_rows` we are making assumptions that left and right columns have the same data type.
