Description
http://hadoop.apache.org/common/docs/r0.20.0/mapred_tutorial.html#Example%3A+WordCount+v1.0
In this example, the classpath is missing commons-cli-2.0-SNAPSHOT.jar
If we compile according to the instructions:
$ javac -classpath /hadoop/core/hadoop-0.20.0-core.jar -d ioperf_classes/ src/WordCount.java
src/WordCount.java:54: cannot access org.apache.commons.cli.Options
class file for org.apache.commons.cli.Options not found
String[] otherArgs = new GenericOptionsParser(conf, args).getRemainingArgs();
The correct compilation should be
$ javac -classpath /hadoop/core/hadoop-0.20.0-core.jar:/hadoop/core/lib/commons-cli-2.0-SNAPSHOT.jar -d ioperf_classes/ src/WordCount.java
