Benchmarking is indeed on the road map for bigtop , as per a recent mailing list thread. Lets add in Terasort / Teragen as a starting point.
Two to note when adding this module:
First - This can be done
1) either in a new test-artifacts submodule (i.e. called benchmarking), or else,
2) it can be added individually into ecosystem components.
Second - Parameterization of the tests from the pom file will make it so that the initial tests really are just smokes, and they can be changed over time to be real performance benchmarks.
