Add more statistics in the web-ui to do with tasks
--------------------------------------------------
Key: HADOOP-1101
URL: https://issues.apache.org/jira/browse/HADOOP-1101
Project: Hadoop
Issue Type: Improvement
Reporter: Devaraj Das
Assigned To: Devaraj Das
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.
