Subject: Getting job ID from within a running task
Content-Type: text/plain; charset=UTF-8; format=flowed

Hi,

I need to be able to retrieve the current job id from within map or 
reduce tasks. I looked here and there, but I wasn't able to find any way 
to do this in the API ...

Basically, I want to be able to do something like this:

class XXX implements Mapper {

    public void configure(Configuration conf) {

       String jobId = ... ?
       String taskId = ... ?
    }
}

And similarly:


class XXX implements Reducer {

    public void configure(Configuration conf) {

       String jobId = ... ?
       String taskId = ... ?
    }
}

Is this possible?
