I'm assuming the reduce phase is failing with the OOME, is that correct?

Could you run "jps -v" to see what the full set of JVM parameters are
for the JVM that is running the task that is failing? I can't imagine
a situation where anywhere near 48GB would be needed, so I'm assuming
that this is a question of your memory settings not being correctly
propagated to the task JVMs somehow.
