Ramya Sunil commented on MAPREDUCE-2789:
----------------------------------------
Eric,
The output looks good and has all the necessary details. Just one more thing,
the number of containers does not give the break up of how many are used by
each of the map and reduce task i.e. information such as 3 map tasks running
using 3 containers and 1 reduce task running using 1 container.
This information is very useful for High RAM jobs. E.g. for a High RAM job
which has 3 map tasks, each requiring 2 containers and 1 reduce task requiring
1 container, displaying the number of containers as 7(6+1) would not convey the
number of containers actually used by each task. Perhaps something like "Map
Containers" and "Reduce containers" would be useful. Thoughts?
