[jira] [Created] (HIVE-21270) A UDTF to show schema (column names and types) of given query

Shubham Chaurasia created HIVE-21270:
----------------------------------------

             Summary: A UDTF to show schema (column names and types) of given query
                 Key: HIVE-21270
                 URL: https://issues.apache.org/jira/browse/HIVE-21270
             Project: Hive
          Issue Type: New Feature
          Components: UDF
            Reporter: Shubham Chaurasia
            Assignee: Shubham Chaurasia


We can get ResultSet metadata using {{ResultSet#getMetaData()}}but JDBC provides no way of getting nested data types(of columns) associated with it. This UDTF helps to retrieve each column name and it's data type.
