> Sentry can ignore the partitions entries which are located in default
> location as they share the same permissions as the table. This will reduce
> the snapshot size decreasing the time to persist the snapshot and also time
> to send the full update to Namenode. This is important as the partition
> information has lion’s share in a HMS Full snapshot. Same approach can be
> taken for tables as well but the issue is that we need to re-construct the
> location based on the database and table names while constructing the ACL for
> the table location. This may increase the CPU overhead. With partitions we
> are safe to ignore the partitions with default location as sentry doesn't
> support permissions on partitions.
