Hi, I am in the middle of setting up a hadoop 2 cluster. I am using the hadoop 2.1-beta tarball.
My cluster has 1 master node running the hdfs namenode, the resourcemanger and the job history server. Next to that I have 3 nodes acting as datanodes and nodemanagers. In order to test, if everything is working, I submitted the teragen job from the hadoop-examples jar like this: $ hadoop jar $HADOOP_PREFIX/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.1.0-beta.jar teragen 1000 /user/vagrant/teragen The job starts up and I get the following output: 13/08/29 14:42:46 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable 13/08/29 14:42:47 INFO client.RMProxy: Connecting to ResourceManager at master.local/192.168.7.10:8032 13/08/29 14:42:48 INFO terasort.TeraSort: Generating 1000 using 2 13/08/29 14:42:48 INFO mapreduce.JobSubmitter: number of splits:2 13/08/29 14:42:48 WARN conf.Configuration: user.name is deprecated.
