I can't answer your question, but I would like to better understand
the
problem you are trying to solve.  The Apache Hadoop/MapReduce java
application isn't really that "large" by modern standards, although it
is generally run with large heap sizes for performance (-Xmx1024m or
larger for the mapred.child.java.opts parameter).

MapReduce is designed to do extremely fast parallel data set
processing
on terabytes of data over hundreds of physical nodes; what advantage
would a pure Python approach have here?
