Subject How to get the read and write time of a hadoop job?
Date Mon, 07 Oct 2013 14:41:19 GMT

For a hadoop job, I can get its execution time by record the job submission
timestamp and the job end timestamp. However, I would like to know the
breakdown of the execution time, such as the time spent actually on reading
the input files and on writing output files. How can I get the read and
write time?
