+The table generation is split in two major phases:
+ * generating a set of random input data and distributing them in the Hadoop cluster over HDFS
+ * running multiple map-reduce jobs to compute the tables from the input data
+
+The mapping phase of each map-reduce job reads one by one secrets from the distributed set of random secrets on the current Hadoop node and generates the chain of Ri and H applications. The result of a MAP instance is a ''<key, value>'' pair with the ''key'' being the end secret and the ''value'' being the start secret of that chain.
