[jira] [Commented] (DRILL-5674) Drill should support .zip compression

["Paul Rogers (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DRILL-5674?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16090772#comment-16090772 ] 

Paul Rogers commented on DRILL-5674:
------------------------------------

Old description:

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}
