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.
