Amar Kamat commented on HADOOP-3200:
------------------------------------
Few comments
1) I think you could use the default job history parser and retrieve counters
inline instead of writing a new listener which will rescan the whole history
file.
2) There is a piece of code in {{TestCounters}} that does counter comparison.
You can reuse that to check counter's content equality.
3) {{JobTracker.getJobCounters()}} can be used to get the job level counters
instead of getting the counters from the task reports and adding/merging them.
> Job history counters should be avaible on the UI.
