>          Issue Type: Bug

>    Affects Versions: 1.9.0, 1.10.0
>         Environment: MacOSX, Drill 1.9

> I have data that is nested in a directory structure.  If I try to execute the following query 
> {code:sql}
> SELECT dir0  
> FROM dfs.`logs/`
> {code}
> I get the following error:
> org.apache.drill.common.exceptions.UserRemoteException: UNSUPPORTED_OPERATION ERROR: With extractHeader enabled, only header names are supported column name columns column index 
> However, if I execute the same query with a second field:
> {code:sql}
> SELECT customer_id, dir0  
> FROM dfs.`logs/`
> {code}
> This query executes without problem.  It would seem as if Drill should support this kind of query.
