Anton Gozhiy reopened DRILL-5554:
---------------------------------
> Wrong error type for "SELECT a" from a CSV file without headers
> ---------------------------------------------------------------
>
> Key: DRILL-5554
> URL: https://issues.apache.org/jira/browse/DRILL-5554
> Project: Apache Drill
> Issue Type: Bug
> Affects Versions: 1.10.0
> Reporter: Paul Rogers
> Priority: Trivial
>
> 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.
