Try and check your classpath, it looks a bit strange: /usp/hdfs: what's this?
Working classpath is: /usr/local/hadoop/etc/hadoop:\ /usr/local/hadoop/share/hadoop/common/lib/*:\ /usr/local/hadoop/share/hadoop/common/*:\ /usr/local/hadoop/share/hadoop/hdfs:\ /usr/local/hadoop/share/hadoop/hdfs/lib/*:\ /usr/local/hadoop/share/hadoop/hdfs/*:\ /usr/local/hadoop/share/hadoop/mapreduce/lib/*:\ /usr/local/hadoop/share/hadoop/mapreduce/*:\ /usr/local/hadoop/share/hadoop/yarn:\ /usr/local/hadoop/share/hadoop/yarn/lib/*:\ /usr/local/hadoop/share/hadoop/yarn/* >Воскресенье, 14 октября 2018, 18:26 +03:00 от r...@post.bgu.ac.il ><r...@post.bgu.ac.il>: > >I tried, I still get the same error. > >On 2018/10/14 15:18:57, ITD < itdir...@mail.ru.INVALID > wrote: >> Class names are case-sensitive in Java, so try >> >> $HADOOP_HOME/bin/hadoop jar >> $HADOOP_HOME/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.9.1.jar Grep >> input output 'dfs[a-z.]+' >> >> >Воскресенье, 14 октября 2018, 18:04 +03:00 от Or Raz < r...@post.bgu.ac.il >> >>: >> > >> >I am using Hadoop 2.9.1 standalone (the folder I am using is after >> >successful compilation of the source code) and whenever I run a Hadoop >> >command such as (where$HADOOP_HOME= /usr/local/hadoop, the directory of >> >Hadoop) >> >$HADOOP_HOME/bin/hadoop jar >> >$HADOOP_HOME/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.9.1.jar >> >grep input output 'dfs[a-z.]+' >> >I get this error : >> >>Error: Could not find or load main class org.apache.hadoop.util.RunJar >> >At first, I was thinking that I am missing some environment variables but >> >are they necessary for the standalone case?
