Review Comment:
Do we need a null check here? I believe this throws if `keyValue.getValue()`
is null.

Review Comment:
You can use `String metadataLocation =
JsonUtil.getStringOrNull(METADATA_LOCATION, node)` for convenience here.

Review Comment:
+1 to this. I find that sometimes, the `TableMetadata` that gets passed has
`null` for `metadataLocation`, in which case we need to use the
`TableMetadataBuilder` to add it which isn't very convenient. 👍
