Description

Rumen's trace generator, built in final form when we install MAPREDUCE-1309 , has features that can parse a history event log in the current format. The testing story on that feature is not good. We can improve it by writing a test case that builds a local single-node cluster, runs a carefully crafted map/reduce job on that cluster, runs the trace generator on the resulting job tracker log, and finally tests the trace for correctness.

• depends upon: MAPREDUCE-1309 I want to change the rumen job trace generator to use a more modular internal structure, to allow for more input log formats
