> Create a CSV file without headers:
> {code}
> 10,foo,bar
> {code}
> Use a CSV storage plugin configured to not skip the first line and not read headers.
> Then, issue the following query:
> {code}
> SELECT a FROM `dfs.data.example.csv`
> {code}
> The result is correct: an error:
> {code}
> org.apache.drill.common.exceptions.UserRemoteException: 
> DATA_READ ERROR: Selected column 'a' must have name 'columns' or must be plain '*'
> {code}
> But, the type of error is wrong. This is not a data read error: the file read just fine. The problem is a semantic error: a query form that is not compatible wth the storage plugin.
> Suggest using {{UserException.unsupportedError()}} instead since the user is asking the plugin to do something that the plugin does not support.
