package org.apache.hadoop.conf does not exist after setting classpath

I am a beginner in hadoop using the hadoop's beginners guide book as a tutorial.

I am using a mac osx 10.9.2 and hadoop version 1.2.1

I have set all the appropriate class path, when I call echo $PATH in terminal:

Here is the result I get:

/Library/Frameworks/Python.framework/Versions/2.7/bin:/Users/oladotunopasina/hadoop-1.2.1/hadoop-core-1.2.1.jar:/Users/oladotunopasina/hadoop-1.2.1/bin:/usr/share/grails/bin:/usr/share/groovy/bin:/Users/oladotunopasina/.rvm/gems/ruby-2.1.1/bin:/Users/oladotunopasina/.rvm/gems/ruby-2.1.1@global/bin:/Users/oladotunopasina/.rvm/rubies/ruby-2.1.1/bin:/usr/local/heroku/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/Users/oladotunopasina/.rvm/bin:/Users/oladotunopasina/.rvm/bin

I tried compiling WordCount1.java and I am getting the following error:

WordCount1.java:2: package org.apache.hadoop.conf does not exist

                         ^

Kindly help.

The CLASSPATH variable is the way to tell applications, including the JDK tools(javac), where to look for user classes.

You can set this variable as given below and try compiling the class.

export CLASSPATH=$CLASSPATH:/Users/oladotunopasina/hadoop-1.2.1/hadoop-core-1.2.1.jar
