> Components: test
> Environment: unix
> Reporter: Alejandro Abdelnur

> While it seems a general problem it is surfacing in streaming TestSymLink testcase with patch for HADOOP-1558
> The contrib testcases use src/contrib/test/hadoop-site.xml.
> The property 'mapred.system.dir' is this file is defined as with a variable '${contrib.name}'.
> The src/build/build-contrib.xml ant file sets the sysproperty 'contrib.name' to the name of the contrib component for the JVM running the testcase.
> The problem is that when a testcase uses MiniMRCluster the TaskRunner forks a JVM for the task and in this JVM (which uses the above hadoop-site.xml) the variable 'contrib.name' is undefined.
> If I hardcode 'streaming' in the hadoop-site.xml for the TestSymLink the testcase works fine.
