----------------------------------
Assignee: (was: Paul Rogers)
> Reading CSV file though table() function does not handle compression
> --------------------------------------------------------------------
>
> 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}
