Hi,
  I am working on a open source project
Nectar<https://github.com/zinnia-phatak-dev/Nectar> where
i am trying to create the hadoop jobs depending upon the user input. I was
using Java Process API to run the bin/hadoop shell script to submit the
jobs. But it seems not good way because the process creation model is
not consistent across different operating systems . Is there any better way
to submit the jobs rather than invoking the shell script? I am using
hadoop-0.21.0 version and i am running my program in the same user where
hadoop is installed . Some of the older thread told if I add configuration
files in path it will work fine . But i am not able to run in that way . So
anyone tried this before? If So , please can you give detailed instruction
how to achieve it . Advanced thanks for your help.

Regards,
Madhukara Phatak

A simple job.submit(…) OR JobClient.runJob(jobConf), submits your job
right from the Java API. Does this not work for you? If not, what
error do you face?

Forking out and launching from a system process is a bad idea unless
there's absolutely no way.

Hi Madhu,

   You can submit the jobs using the Job API's programmatically from any
system. The job submission code can be written this way.

     // Create a new Job
     Job job = new Job(new Configuration());
     job.setJarByClass(MyJob.class);
    
     // Specify various job-specific parameters    
     job.setJobName("myjob");
    
     job.setInputPath(new Path("in"));
     job.setOutputPath(new Path("out"));
    
     job.setMapperClass(MyJob.MyMapper.class);
     job.setReducerClass(MyJob.MyReducer.class);

     // Submit the job
     job.submit();

For submitting this, need to add the hadoop jar files and configuration
files in the class path of the application from where you want to submit the
job.

You can refer this docs for more info on Job API's.

Hi
 I am using the same APIs but i am not able to run the jobs by just adding
the configuration files and jars . It never create a job in Hadoop , it just
shows cleaning up staging area and fails.

Madhu,

Do you get a specific error message / stack trace? Could you also
paste your JT logs?

I am using JobControl.add() to add a job and running job control in
a separate thread and using JobControl.allFinished() to see all jobs
completed or not . Is this work same as Job.submit()??

Yes. Internally, it calls regular submit APIs.

Madhu,

 Can you check the client logs, whether any error/exception is coming while
submitting the job?

Hi
I am submitting the job as follows

java -cp

I get the log in CLI as below

It doesn't create any job in hadoop.

Madhu,

Ditch the '*' in the classpath element that has the configuration
directory. The directory ought to be on the classpath, not the files
AFAIK.

Try and let us know if it then picks up the proper config (right now,
its using the local mode).

My code to submit jobs (via a declarative configuration) is up online

http://smartfrog.svn.sourceforge.net/viewvc/smartfrog/trunk/core/hadoop-components/hadoop-ops/src/org/smartfrog/services/hadoop/operations/components/submitter/SubmitterImpl.java?revision=8590&view=markup

It's LGPL, but ask nicely and I'll change the header to Apache.

That code doesn't set up the classpath by pushing out more JARs (I'm
planning to push out .groovy scripts instead), but it can also poll for
job completion, take a timeout (useful in small test runs), and do other
things. I currently mainly use it for testing

Thank you . Will have a look on it.

Thank you Harsha . I am able to run the jobs by ditching *.
