> Unify and Clean Up Desc Commands Using Catalog Interface
> --------------------------------------------------------
>
> Key: SPARK-20067
> URL: https://issues.apache.org/jira/browse/SPARK-20067
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.1.0
> Reporter: Xiao Li
> Assignee: Xiao Li
> Fix For: 2.2.0
>
>
> We should unify and clean up the outputs of `DESC EXTENDED/FORMATTED` and
> `SHOW TABLE EXTENDED` by moving the logics into the Catalog interface. The
> output formats are improved. We also add the missing attributes. It impacts
> the DDL commands like `SHOW TABLE EXTENDED`, `DESC EXTENDED` and `DESC
> FORMATTED`.
> In addition, by following what we did in Dataset API `printSchema`, we can
> use `treeString` to show the schema in the more readable way.
