Hadoop 2 map reduce builld.xml

basic_mapred_build.xml

<!-- 
     Ever since Hadoop 2 deprecated hadoop-core.jar, building mapreduce jars isn't straightforward
     especially if you want to use newer bits.
     
     I just use this template ant build.xml that includes all hadoop jars, aaaaand all them variations 
     of the same lib jars that hadoop jars depend on.  
     
     hadoop.home is set to OS X homebrew, switch to whatever home is for the distribution.
