sakurai commented on MAPREDUCE-806:
-----------------------------------
i came across here as i happened to be facing the same problem.
everything goes well after i followed the instruction here(no errors after
this), but i cant see any wordcount.jar created..
javac -classpath
/home/hadoop/hadoop/hadoop-core-1.0.3.jar:/home/hadoop/hadoop/lib/commons-cli-1.2.jar
-d classes src/WordCount.java
i only have the following classes created.
-rw-rw-r-- 1 hadoop hadoop 1790 Aug 7 15:42 WordCount$TokenizerMapper.class
-rw-rw-r-- 1 hadoop hadoop 1789 Aug 7 15:42 WordCount$IntSumReducer.class
-rw-rw-r-- 1 hadoop hadoop 1911 Aug 7 15:42 WordCount.class
sorry, i am not familiar with java, can someone tell me if my compiling is
correct?
thank you.

> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: examples
> Affects Versions: 0.20.1
> Environment: linux
> Reporter: Hector Yuen
> Priority: Trivial
>
> 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
