> JobConf.findContainingJar incorrectly transforms paths containing '+'

> Key: MAPREDUCE-2370
> 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.
