Anastasis Andronidis commented on MAPREDUCE-806:
------------------------------------------------

The file you are looking for in hadoop-0.21.0 is in HADOOP_HOME/lib/commons-cli-1.2.jar It is not ver 2.0 but worked for me.

> 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
