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: Improvement
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!
