JobTracker web interface at http://localhost:50030/ provides a nice view, in a web browser, of the jobs running in the cluster. For a given job, one can also find the path to the jar file that represents the binary for that job. This info is part of the 'JobFile'. http://localhost:50030/jobconf.jsp?jobid=job_200801291432_0014 The property of interest is mapred.jar, whose value is the absolute path to the binary jar file. "/tmp/hadoop-153/hadoop-root/mapred/local/jobTracker/job_200801291432_0014.jar"
I would like to convert this absolute path of a job's binary jar file, to a HTML link, so that the user can click that link and potentially download it. The question is what is the best way to do this. Requesting help from the dev. team please on the best way to do this. For now we can ignore the security and the short time-to-live for the link to be valid (as the target jar file is deleted once the job completes). I still need to find a way to expose this file. One thought that occurred to me was to potentially write a custom jobconf.xsl and convert the entries in the 'value' column ending in ".jar" (there is only one) to a link. Thanks for your time. rahul
