> Currently, the web-ui does not display all the statistics needed to analyze performance
of a job in the MR framework. Things like the average time the maps took to finish is missing.
Similarly, the min/max/average for shuffle is missing. It would also be nice to add the statistics
for major transitions like the time when the last map finished, the time when the last shuffle/copy
finished, etc. The rate of reading map input and writing reduce output will be helpful too.
