Todd Lipcon commented on IMPALA-7539:
-------------------------------------
One consideration about this: this is actually a big performance hit for
loading tables in the legacy catalog v1 mode.
I think we should consider doing this only for external tables that we see are
outside of the warehouse directory. If a table's in the warehouse, we should
just assume it's writable.

> LocalTable currently stubs out checks for whether tables and partitions are
> writable. This means that inserts into non-writable partitions will pass
> planning and fail during execution. We should likely implement these checks,
> or decide that this feature is unnecessary (it's quite expensive)
