>                 Key: DRILL-5674
>                 URL: https://issues.apache.org/jira/browse/DRILL-5674
>             Project: Apache Drill
>          Issue Type: Bug
>    Affects Versions: 1.10.0
>            Reporter: Paul Rogers
>
> Create a compressed CSV file with column headers: data.csv.zip.
> Define a storage plugin config for the file, call it "dfs.myws", set delimiter = ",",
extract header = true, skip header = false.
> Run a simple query:
> SELECT * FROM dfs.myws.`data.csv.zip`
> This works fine.
> Now, do the same thing, but using a table function:
> {code}
> SELECT * FROM table(dfs.myws.`data.csv.zip` (type => 'text', fieldDelimiter =>
',' , extractHeader => true))
> {code}
> This does not work. Apparently, the reader tries to read the zip file as if it were an
uncompressed file:
> {code}
> DATA_READ ERROR: Drill failed to read your text file.  Drill supports up to 65536 columns
in a text file.  Your file appears to have more than that.
> Failure while reading file file:/Users/fred/data/data.csv.zip. Happened at or shortly
before byte position 121177.
> {code}
