[jira] [Commented] (MAPREDUCE-806) WordCount example does not
compile given the current instructions
[ https://issues.apache.org/jira/browse/MAPREDUCE-806?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13213236#comment-13213236 ]
Abhay Bhangale commented on MAPREDUCE-806:
------------------------------------------
Thanks. That helped.
$ pwd
/home/abhay/sandbox/hadoop-0.20.203.0
$ find * -iname commons-cli-*.jar
lib/commons-cli-1.2.jar
$ javac -cp hadoop-core-0.20.203.0.jar:lib/commons-cli-1.2.jar -d playground/classes playground/src/WordCount.java
And it compiled fine!

> Key: MAPREDUCE-806
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-806
> 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
