I want to try hadoop example,but it raise following error,where is wrong,how to correct? Thanks.
[root@localhost ~]# useradd -g hadoop yarn
useradd: user 'yarn' already exists
[root@localhost ~]# gpasswd -a hdfs hadoop
Adding user hdfs to group hadoop
[root@localhost ~]# su - hdfs
[hdfs@localhost ~]$ cd /opt/yarn/hadoop-2.2.0/bin/
[hdfs@localhost bin]$ export YARN_EXAMPLES=/opt/yarn/hadoop-2.2.0/share/hadoop/mapreduce
[hdfs@localhost bin]$ ./yarn jar /opt/yarn/hadoop-2.2.0/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.2.0.jar pi 16 1000
Number of Maps = 16
Samples per Map = 1000
