Including third party jar files in Map Reduce job
Hi All,
I am new to Hadoop and was trying to generate random numbers using apache commons math library.
I used Netbeans to build the jar file and the manifest has path to commons-math jar as lib/commons-math3.jar
I have placed this jar file in HADOOP_HOME/lib folder but still I am getting ClassNotFoundException.
I tried using -libjar option with $HADOOP_HOME/bin/Hadoop jar myprg.jar <inputpath> <outputpath> -libjar <jarpath>
And $HADOOP_HOME/bin/Hadoop jar myprg.jar -libjar <jarpath> <inputpath> <outputpath>
But this is not working. Please help.
Thanks and Regards
Utkarsh Gupta

Posted by Utkarsh Gupta <Ut...@infosys.com>.
I have tried implementing Tool interface as mentioned @ http://hadoop.apache.org/common/docs/current/api/org/apache/hadoop/util/Tool.html
But -libjars option is not working.
I have copied the jar to all the nodes at $HADOOP_HOME/lib folder
But I am still getting the same error. The map task completes for master node (also acting as worker) from where job is run, but the task is failing on all the other nodes
The stack trace is :

As Bejoy mentioned,
If you have copied the jar to $HADOOP_HOME, then you should copy it to all the nodes in the cluster. (or)
If you want to make use of -libjar option, your application should implement Tool to support generic options. Please check the below link for more details.

Hi Utkarsh
You can add third party jars to your map reduce job elegantly in the following ways
1) use - libjars
hadoop jar jarName.jar com.driver.ClassName -libjars /home/some/dir/somejar.jar ....
2) include the third pary jars in /lib folder while packaging your application
3) If you are adding the jar in HADOOP_HOME/lib , you need to add this at all nodes.

Hi Utkarsh,
The usage of the jar command is like this,
Usage: hadoop jar <jar> [mainClass] args...
If you want the commons-math3.jar to be available for all the tasks you can do any one of these 1. Copy the jar file in $HADOOP_HOME/lib dir or 2. Use the generic option -libjars.
Can you give the stack trace of your problem for which class it is giving ClassNotFoundException(i.e for main class or math lib class)?
Thanks

Hi Harsh,
This worked this was exactly what I was looking for.
The warning has gone and now I can add third party jar files using DistributedCache.addFileToClassPath() method.
Now there is no need to copy jar to each node's $HADOOP_HOME/lib folder
Thanks a lot

I wish I knew that when I needed it, but it's not too late know either.
Thanks Harsh, you're doing a great job.

RE: Including third party jar files in Map Reduce job
Posted by Utkarsh Gupta <Ut...@infosys.com>.
Hi Harsh,
I have implemented Tool like this
public static void main(String[] args) throws Exception {
Configuration configuration = new Configuration();
int rc = ToolRunner.run(configuration, new WordCount(), args);
System.exit(rc);
}
@Override
public int run(String[] args) throws Exception {
if (args.length < 2) {
System.err.println("Usage: WordCount <input path> <output path>");
return -1;
}
Configuration conf = new Configuration();
//conf.set("mapred.job.tracker", "local");
Job job = new Job(conf, "wordcount");
job.setJarByClass(WordCount.class);
job.setMapperClass(MyMapper.class);
job.setReducerClass(MyReducer.class);
job.setOutputKeyClass(Text.class);
job.setOutputValueClass(IntWritable.class);
job.setInputFormatClass(TextInputFormat.class);
job.setOutputFormatClass(TextOutputFormat.class);
job.setNumReduceTasks(1);
FileInputFormat.addInputPath(job, new Path(args[0]));
FileOutputFormat.setOutputPath(job, new Path(args[1]));
return (job.waitForCompletion(true)) ? 0 : 1;
}
This is working but I am unable to figure out why still it is warning

Utkarsh,
A log like "12/04/04 15:21:00 WARN mapred.JobClient: Use GenericOptionsParser for parsing the arguments. Applications should implement Tool for the same." indicates you haven't implemented the Tool approach properly (or aren't calling its run()).

Hi Utkarsh
You can add third party jars to your map reduce job elegantly in the following ways
1) use - libjars
hadoop jar jarName.jar com.driver.ClassName -libjars /home/some/dir/somejar.jar ....
2) include the third pary jars in /lib folder while packaging your application
3) If you are adding the jar in HADOOP_HOME/lib , you need to add this at all nodes.

Hi Utkarsh,
The usage of the jar command is like this,
Usage: hadoop jar <jar> [mainClass] args...
If you want the commons-math3.jar to be available for all the tasks you can do any one of these 1. Copy the jar file in $HADOOP_HOME/lib dir or 2. Use the generic option -libjars.
Can you give the stack trace of your problem for which class it is giving ClassNotFoundException(i.e for main class or math lib class)?

Hi Utkarsh,
The usage of the jar command is like this,
Usage: hadoop jar <jar> [mainClass] args...
If you want the commons-math3.jar to be available for all the tasks you can do any one of these 1. Copy the jar file in $HADOOP_HOME/lib dir or 2. Use the generic option -libjars.
Can you give the stack trace of your problem for which class it is giving ClassNotFoundException(i.e for main class or math lib class)?
Thanks
Devaraj

Subject: Including third party jar files in Map Reduce job
Hi All,
I am new to Hadoop and was trying to generate random numbers using apache commons math library.
I used Netbeans to build the jar file and the manifest has path to commons-math jar as lib/commons-math3.jar I have placed this jar file in HADOOP_HOME/lib folder but still I am getting ClassNotFoundException.
I tried using -libjars option with $HADOOP_HOME/bin/Hadoop jar myprg.jar <inputpath> <outputpath> -libjars <jarpath> And $HADOOP_HOME/bin/Hadoop jar myprg.jar -libjar <jarpath> <inputpath> <outputpath> But this is not working. Please help.
Thanks and Regards

Re: Including third party jar files in Map Reduce job

Hi Utkarsh
You can add third party jars to your map reduce job elegantly in
the following ways
1) use - libjars
hadoop jar jarName.jar com.driver.ClassName -libjars
/home/some/dir/somejar.jar ....
2) include the third pary jars in /lib folder while packaging your
application
3) If you are adding the jar in HADOOP_HOME/lib , you need to add this at
all nodes.
