Subject Re: Example of chain map red

JJ,

Apart from javadocs, test cases are a good way to read examples. These
can be found in your $HADOOP_HOME/src/test source directories.

If you are asking about ChainMapper and ChainReducer, see
http://svn.apache.org/repos/asf/hadoop/common/branches/branch-0.20-security/src/test/org/apache/hadoop/mapred/lib/TestChainMapReduce.java
(Method: testChain(…))

Or perhaps you instead need JobControl, for which you can see:
http://svn.apache.org/repos/asf/hadoop/common/branches/branch-0.20-security/src/test/org/apache/hadoop/mapred/jobcontrol/TestJobControl.java
