Experience the hair-raising, white-knuckle, thrills, spills* and excitement of Apache Hadoop MapReduce without the inconvenience of setting up a cluster of your own. (* no pun intended)
Usage: ./simmapreduce.sh [level] (default="beginner")
-
Test your patience and boredom threshold to the limit with the configurable BIG DATA level. Choose between "beginner", "intermediate" and "expert" for an increasingly realistic MapReduce experience.
-
Witness first-hand the terrifying effects of reducer skew, where those final couple of percent just take so much longer.
-
Impress your friends and family with huge numbers on job completion. Are those gigabytes? Terabytes? Surely not petabytes!? Who really knows without handy separators between digits.
-
COMING SOON: failed task simulator. Because nothing says f-you like a 99% completion going back to 98.
Enjoy!
