Summary: Enhance describe frame work to describe the output of a
query
Key: SPARK-26982
URL: https://issues.apache.org/jira/browse/SPARK-26982
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.4.0
Reporter: Dilip Biswal
Currently we can use `df.printSchema` to discover the schema information for a
query. We should have a way to describe the output schema of a query using SQL
interface.
Example:
DESCRIBE SELECT * FROM desc_table
DESCRIBE QUERY SELECT * FROM desc_table
