I use hadoop 2.2.0 under Redhat Linux,I run hadoop mapreduce examples like
follows:
[yarn@localhost sbin]$ hadoop jar
/opt/yarn/hadoop-2.2.0/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.2.0.jar
pi
-Dmapreduce.clientfactory.class.name=org.apache.hadoop.mapred.YarnClientFactory
-libjars
The pi job does not leave any HDFS data. You can see its result on the
console: Estimated value of Pi is 3.14127500.
What are you trying to really test or do here? If you want data on
HDFS, you can load it up via 'hadoop fs -put', or generate it with
teragen, etc.?
