Tasks run by MiniMRCluster don't get sysprops from TestCases
------------------------------------------------------------
Key: HADOOP-1587
URL: https://issues.apache.org/jira/browse/HADOOP-1587
Project: Hadoop
Issue Type: Bug
Components: test
Environment: unix
Reporter: Alejandro Abdelnur
Priority: Blocker
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.
