--------------------------------------

             Summary: Describe table returns no rows for Parquet / JSON / Text
                 Key: DRILL-2284
                 URL: https://issues.apache.org/jira/browse/DRILL-2284
             Project: Apache Drill
          Issue Type: Bug
          Components: Metadata
            Reporter: Abhishek Girish
            Assignee: Steven Phillips
            Priority: Minor
             Fix For: 0.8.0


'Describe' table should either support displaying schema information or fail indicating the
lack of support for Parquet / JSON / Text 

Currently no rows are returned, which might confuse an end user

*Parquet/JSON/Text:*
> describe store_sales;
+--+
|  |
+--+
+--+
No rows selected (0.07 seconds)

*Hive:* 
> describe region;
