             Summary: FileTargetImpl cuts off extensions of output files
                 Key: CRUNCH-228
                 URL: https://issues.apache.org/jira/browse/CRUNCH-228
             Project: Crunch
          Issue Type: Bug
            Reporter: Dave Beech


Compressed files written by mapreduce often have extensions, e.g. '.deflate', 
'.gz' or '.snappy'. Crunch currently cuts off these extensions during the move 
of output files to their final destination, which is fine in some circumstances 
but causes problems in others. 

For example, running 'hadoop fs -text myfile.deflate' will show the 
decompressed text on screen but running 'hadoop fs -text myfile' on a 
deflate-compressed file with no extension prints unreadable compressed data 
instead.
