Using Counters in Dumbo

[Samarth Gahire]

Hi ,
    I have written a hadoop job which retrieves some mapping values from the Database, and if the mapping is not present in the database it makes a call to webservice.
I have to count how many webservice call my job did in a single run.
I think this is possible with counters in dumbo{ e.g self.counters["No Of Call To Webservice"] += 1 } but not getting  where to look for this counter value.

should be in the stats of your job, look at the job tracker page it should be there.

You can run the command:

hadoop job -counter <job-id> Program "No Of Call To Webservice"

or for a full list:

hadoop job -status <job-id>
