Subject [jira] Created: (MAPREDUCE-714) JobConf.findContainingJar unescapes unnecessarily on Linux

JobConf.findContainingJar unescapes unnecessarily on Linux

                 Key: MAPREDUCE-714
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-714
             Project: Hadoop Map/Reduce
          Issue Type: Bug
            Reporter: Todd Lipcon

In JobConf.findContainingJar, the path name is decoded using URLDecoder.decode(...). This
was done by Doug in r381794 (commit msg "Un-escape containing jar's path, which is URL-encoded.
 This fixes things primarily on Windows, where paths are likely to contain spaces.") Unfortunately,
jar paths do not appear to be URL encoded on Linux. If you try to use "hadoop jar" on a jar
with a "+" in it, this function decodes it to a space and then the job cannot be submitted.
