Consider the following transactional dataset with $5$ records. The minimum support value is $2(0\mathrm{.}4).$ Use Apriori algorithm to generate all rules that support $>0\mathrm{.}3,$ confidence $>0\mathrm{.}4.$ Show the detailed steps. $(20$ points$)$

Design a MapReduce solution for Apriori algorithm? The input is transactional, but too massive for single memory. You can use more than one runs of MapReduce. Please show the format the $$ key, value$>$ pairs, Map functions, and Reduce functions. $(20$ points$)$
