Josh Wills commented on CRUNCH-632:
-----------------------------------
Agree that this would be worthwhile, but I'm concerned that I don't know the
CSVFileSource impl well enough to do this safely (or what the minimal change
would be that would satisfy this.) [~mkwhitacre], would you mind asking around?

> Add compression support for CSVFileSource

> Key: CRUNCH-632
> URL: https://issues.apache.org/jira/browse/CRUNCH-632
> Project: Crunch
> Issue Type: Improvement
> Reporter: Jim McStanton
> Priority: Minor
>
> Currently CSVFileSource does not support decompressing files before reading
> them, and simply opens the file and starts reading the contents:
> https://github.com/apache/crunch/blob/6280983179e9c690af69c2bf0e296b054122d724/crunch-core/src/main/java/org/apache/crunch/io/text/csv/CSVRecordReader.java#L127.
>
> This source would more closely match TextFileSource if this support was
> added. The {{LineRecordReader}} supports this behavior
> [here|http://grepcode.com/file/repo1.maven.org/maven2/org.apache.hadoop/hadoop-mapreduce-client-core/2.7.1/org/apache/hadoop/mapreduce/lib/input/LineRecordReader.java?av=f#87].
