Oh, and reading your original comment more carefully: yeah, they are two
separate entities (one for the table partition, and one for the index
partition), so even if the equals method were tied to metastore object
identity, it still wouldn't work.
The getSpec() method on the Partition class is what gives you the actual
key/value pairs for the partition, suitable for comparison.
