> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 1.6.1
> Reporter: Tejas Patil
> Assignee: Apache Spark
> Priority: Trivial
>
> For bucketed tables in Hive, one can also add constraint about column
> sortedness along with ordering.
> As per the spec in [0], CREATE TABLE statement can allow SORT ordering as
> well:
> [CLUSTERED BY (col_name, col_name, ...) [SORTED BY (col_name [ASC|DESC],
> ...)] INTO num_buckets BUCKETS]
> See [1] for example.

> [1] :

> Currently CatalogTable does not store any information about the sort ordering
> and just has the names of the sorted columns.
