JAR does not exist or is not a normal file

While running the wordcount example in Hadoop, I am facing the following error. 

saying "JAR does not exist or is not a normal file: 
/usr/local/hadoop/share/hadoop/mapreduce/hadoop-mapreduceexamples-2.2.0.jar"

My input command was : 

hadoop jar $HADOOP_HOME/share/hadoop/mapreduce/hadoop-mapreduceexamples-2.2.0.jar  wordcount input output
Solution

  • Just go to that path and check it out if the name is correct or not, the convention may differ by the distribution.

    For example, hadoop 3.1.0 has it in the following path:

    $HADOOP_HOME/share/hadoop/mapreduce/hadoop-mapreduce-examples-3.1.0.jar
