Hi Joan, In 2.7.1 i am able to see <installation folder>/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.7.1.jar which can help you run some sample MapRed Examples like wordcount/ PI
naga@<hostname>:/opt/install/hadoop-2.7.1/bin$ ./yarn jar ../share/hadoop/mapreduce/hadoop-mapreduce-examples-2.7.1.jar Listening for transport dt_socket at address: 7003 An example program must be given as the first argument. Valid program names are: aggregatewordcount: An Aggregate based map/reduce program that counts the words in the input files. aggregatewordhist: An Aggregate based map/reduce program that computes the histogram of the words in the input files. bbp: A map/reduce program that uses Bailey-Borwein-Plouffe to compute exact digits of Pi. dbcount: An example job that count the pageview counts from a database. distbbp: A map/reduce program that uses a BBP-type formula to compute exact bits of Pi. ...
