hadoop:Not able to run a mapreduce job

Question

I have made 3 files in java,made a jar file and wrote this line to execute the MapReduce code:

hadoop jar /home/xyz/Documents/hadoop-2.7.3/abc1.jar woq.WordCount /test/vocab.txt /test/output3

The jar filename is abc1.jar , woq is the package name and WordCount is the main class in which the job is defined for mapreduce code.When this line is executed,following error is displayed:

Exception in thread "main" java.lang.ClassNotFoundException: woq.WordCount
    at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
    at java.lang.Class.forName0(Native Method)

    at org.apache.hadoop.util.RunJar.run(RunJar.java:214)
    at org.apache.hadoop.util.RunJar.main(RunJar.java:136)

Any suggestions on what I point am I missing in executing the above line?

Answer 1

From the comments,

The class files appear to have the line package woq; in them without the acutal directory structure. You can either create a parent directory woq or remove that line from the files and recompile it.

If you remove the line, you can submit the job like this

hadoop jar /home/xyz/Documents/hadoop-2.7.3/abc1.jar WordCount /test/vocab.txt /test/output3
