[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.
