>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2370
>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>          Components: job submission
>    Affects Versions: 0.20.3
>            Reporter: Tony Valderrama
>            Priority: Minor

> Due to the usage of URLDecoder in JobConf#findContainingJar, the path will be incorrectly
modified if it contains the '+' character.  URLDecoder is intended for HTML form data (application/x-www-form-urlencoded),
so all '+' will be converted to ' '.
> This is easy to reproduce - install hadoop at a path which contains a '+' character and
try to run a distcp job.  Mapreduce will fail to locate hadoop-tools.jar.  I have only investigated
this error on 0.20.3-rc2.
> Below is the exception which indicate the failure (correct path is /home/user/build/hadoop-core-0.20.3+8/hadoop-tools-0.20.3+8.jar):
> Copy failed: java.io.FileNotFoundException: File /home/user/build/hadoop-core-0.20.3
8/hadoop-tools-0.20.3 8.jar does not exist.
