#### Word Count Example
wget http://www.gutenberg.org/cache/epub/1661/pg1661.txt
hdfs dfs -mkdir /samples/input
hdfs dfs -put pg1661.txt /samples/input
hadoop jar $HADOOP_INSTALL/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.6.0.jar wordcount /samples/input /samples/output
hdfs dfs -cat /samples/output/part* | less

#### PI calculation example with 16 maps and 100000 samples, run the following command:
hadoop jar $HADOOP_INSTALL/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.6.0.jar pi 16 100000

#### To see all examples run the following command:
hadoop jar $HADOOP_INSTALL/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.6.0.jar
