[jira] [Created] (DRILL-5554) Wrong error type for "SELECT a" from
a CSV file without headers
Paul Rogers created DRILL-5554:
----------------------------------
Summary: 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.
