map-reduce-pattern-matching's Introduction

Map-Reduce-Pattern-Matching

This project implements the Quick-Search algorithm for pattern matching on large document. Quick-Search algorithm is a variant of Boyer-Moore algorithm that uses only the bad character match rule. Distributed version of the algorithm is implemented using Hadoop Map-Reduce framework. Navie and Quick-Search pattern matching algorithms are compared along with their distributed versions for execution time and chunk-size.

Running the program

  • Generate the input file and corresponding pattern to be matched(This may take few seconds) python3 gen_input.py

  • For distributed setting:-

    • Run ./run_navie.sh for Navie search.
    • Run ./run_qs.sh for Quick-Search

  • For normal setting:-

    • Run javac NavieSearch.java and java NavieSearch sample_temp.txt key_temp.txt for Navie search
    • Run javac QuickSearch.java and java QuickSearch sample_temp.txt key_temp.txt for Quick-Search
