A simple Bash script to do map-reduce style computations on distributed data. Designed to analyze log files stored locally on many hosts. For each host listed, the map.sh script is executed remotely and should return a key-value pair separated by whitespace. The values returned from each host is then piped to the reduce.sh script. The output of that script is printed to stdout.
