If you have Hadoop installed on your machine,you can use the following two ways to generate data.

3.hadoop jar /usr/lib/hadoop-0.20-mapreduce/hadoop-examples.jar randomwriter /random-data

generates 10 GB data per node under folder /random-data in HDFS.

hadoop-examples.jar randomtextwriter /random-text-data

cd /usr/local/hadoop
hadoop jar ./share/hadoop/mapreduce/hadoop-mapreduce-examples-2.7.1.jar randomtextwriter /random-text-data
