Splittable Gzip
---------------

                 Key: HADOOP-7076
                 URL: https://issues.apache.org/jira/browse/HADOOP-7076
             Project: Hadoop Common
          Issue Type: New Feature
          Components: io
            Reporter: Niels Basjes


Files compressed with the gzip codec are not splittable due to the nature of 
the codec.
This limits the options you have scaling out when reading large gzipped input 
files.

Given the fact that gunzipping a 1GiB file usually takes only 2 minutes I 
figured that for some use cases wasting some resources may result in a shorter 
job time under certain conditions.
So reading the entire input file from the start for each split (wasting 
resources!!) may lead to additional scalability.
