> Project: Apache Arrow
> Issue Type: Bug
> Reporter: Andrew Lamb
> Assignee: Andrew Lamb
> Priority: Major
> Attachments: repro.csv
>
>
> I was trying to write a reproducer for another bug, and I hit this one:
> Repro:
> {code}
> CREATE EXTERNAL TABLE repro
> STORED AS CSV
> LOCATION 'repro.csv';
> select * from repro;
> {code}
> The contents of repro.csv are as follows (also attached):
> {code}
> a,b
> 1,100
> 1,200
> 2,100
> 2,200
> 2,300
> {code}
> Expected behavior: a table of 2 columns, 5 rows is returned
> Actual behavior: A panic occurs:
> {code}
> > select * from repro;
> thread 'main' panicked at 'index out of bounds: the len is 0 but the index is
> 0', datafusion/src/optimizer/projection_push_down.rs:238:31
> note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
> {code}
> I'll try and look into it myself, but I wanted to get the repro up first.
