DistributedCache.addArchiveToClassPath doesn't work
---------------------------------------------------
Key: MAPREDUCE-752
URL: https://issues.apache.org/jira/browse/MAPREDUCE-752
Project: Hadoop Map/Reduce
Issue Type: Bug
Reporter: Vladimir Klimontovich
addArchiveToClassPath is a method of DistributedCache class. It should be
called before running a task. It accepts path to a jar file on a DFS. After it
this method should put this jar file on sitribuuted cache and than add this
file to classpath to each map/reduce process on job tracker.
This method don't work:
in TaskRunner there is an algorithm that looks for correspondence between DFS
paths and local paths in distributed cache.
It compares
if (archives[i].getPath().equals(
archiveClasspaths[j].toString())){
instead of
if (archives[i].toString().equals(
archiveClasspaths[j].toString()))
