> This is the exact code snippet:
> {noformat}
> / Since there is no easy way of knowing whether MAPREDUCE-1597 is present in
> the tree or not,
> // we use a configuration variable for the same
> if (this.mrwork != null && !this.mrwork.getHadoopSupportsSplittable()) {
> // The following code should be removed, once
> // https://issues.apache.org/jira/browse/MAPREDUCE-1597 is fixed.
> // Hadoop does not handle non-splittable files correctly for
> CombineFileInputFormat,
> // so don't use CombineFileInputFormat for non-splittable files
> //ie, dont't combine if inputformat is a TextInputFormat and has
> compression turned on
> {noformat}
