 Review comment:
   To keep it simple, I would suggest to
   1. remove the explicit ``
   2. and add a new environment variable `NUTCH_HADOOP_OPTS` which is used to add further
options to the commonOptions
   In local mode it's still sufficient to use the environment variable NUTCH_OPTS to set the
Java heap size. In distributed mode, this would allow fine-grained memory settings, e.g.
   export NUTCH_HADOOP_OPTS=""
   These are required, as the Java heap must be lower than the total memory allocated for
a map/reduce task.
