Song Jun commented on SPARK-19257:
----------------------------------
I found it than `CatalogTablePartition` and `CatalogTable` use the same class
`CatalogTableStorageFormat`.
if we change CatalogTableStorageFormat 's locationUri from `String` to `URI`,
this will failed in `CatalogTablePartition` because table partition location
can have whitespace, such as `2014-01-01 00%3A00%3A00`， while this is not a
legal URI (no encoded whitespace)
> The type of CatalogStorageFormat.locationUri should be java.net.URI instead
> of String

> Currently we treat `CatalogStorageFormat.locationUri` as URI string and
> always convert it to path by `new Path(new URI(locationUri))`
> It will be safer if we can make the type of
> `CatalogStorageFormat.locationUri` java.net.URI. We should finish the TODO in
