[jira] [Created] (DRILL-5673) NPE from planner when using a table
function with an invalid table
Paul Rogers created DRILL-5673:
----------------------------------
Summary: NPE from planner when using a table function with an invalid table
Key: DRILL-5673
URL: https://issues.apache.org/jira/browse/DRILL-5673
Project: Apache Drill
Issue Type: Bug
Affects Versions: 1.10.0
Reporter: Paul Rogers
Create a CSV file, with headers and call it "data_3.csv."
Set up a storage plugin config with headers, delimiter of ",". Call it "myws". Then read the file:
{code}
SELECT * FROM `dfs.myws`.`data_3.csv`
{code}
This query works.
Try the same with a table function:
{code}
SELECT * FROM table(dfs.myws.`data_3.csv` (type => 'text', fieldDelimiter => ',' , extractHeader => true))
{code}
This also works.
Now, let's use an incorrect name:
{code}
SELECT * FROM `dfs.myws`.`data_33.csv`
{code}
(Note the "33" in the name.)
This produces an error to the client:
Now the bug. Do the same thing with the table function:
{code}
SELECT * FROM table(dfs.myws.`data_33.csv` (type => 'text', fieldDelimiter => ',' , extractHeader => true))
{code}
This results in an NPE:
{code}

This bug causes much user confusion as the user cannot immediately tell that this is "user error" vs. something terribly wrong with Drill.
