Johannes Zillmann updated MAPREDUCE-1581:
-----------------------------------------
Issue Type: Bug (was: Improvement)
> DistributedCache#addXxxToClassPath() fails silently if qualified pathes are
> passed in
> -------------------------------------------------------------------------------------
>
> Key: MAPREDUCE-1581
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-1581
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: distributed-cache
> Reporter: Johannes Zillmann
> Priority: Minor
>
> In both methods (addFileToClassPath & addArchiveToClassPath) you can specify
> a path. If this path is fully qualified (hdfs:///....) the files are not in
> the job classpath.
> (since the : in the path is also used as path separator).
> So i think with one of the following simple improvements:
> - throw an exception if the specified path is fully qualified
> - OR disqualify the path (f.e. with new Path(path.toUri().getPath()))
> people would have an easier start with the DistributedCache!
