Amar Kamat commented on MAPREDUCE-2408:
---------------------------------------
The goal of this jira is to emulate the compression characteristics of a
MapReduce job. Emulating compression characteristics involves the following 1.
Generating compressible data. The compression characteristics (e.g compression
ratio) of the data (map input, map output and reduce output) should be
configurable. 2. Extract compression related properties from original job's
configuration and history files. Configure the simulated job to mimic the
compression behavior using the original job's configuration and history.
> Make Gridmix emulate usage of data compression
