I'm quite new in this field but I'm trying to analyze some MapReduce jobs and create graphs with memory usage, cpu usage and others relevant parameters.
I can only use MapReduce Counters for different reasons, with your experience what are the best indicators to calculate with these?
In particular, I have to compare the performance of the same Job with different number of reducers, or different datasets sizeI can't use chart created by cloudera manager
I would request you to review Comparing Similar Activities
Hope that helps.
