             Summary: 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].
