> To emulate distributed cache usage in gridmix jobs, there are 9 configuration
> properties needed to be available in trace file:
> (1) mapreduce.job.cache.files
> (2) mapreduce.job.cache.files.visibilities
> (3) mapreduce.job.cache.files.filesizes
> (4) mapreduce.job.cache.files.timestamps
> (5) mapreduce.job.cache.archives
> (6) mapreduce.job.cache.archives.visibilities
> (7) mapreduce.job.cache.archives.filesizes
> (8) mapreduce.job.cache.archives.timestamps
> (9) mapreduce.job.cache.symlink.create
> To emulate data compression in gridmix jobs, trace file should contain the
> following configuration properties:
> (1) mapreduce.map.output.compress
> (2) mapreduce.map.output.compress.codec
> (3) mapreduce.output.fileoutputformat.compress
> (4) mapreduce.output.fileoutputformat.compress.codec
> (5) mapreduce.output.fileoutputformat.compress.type
> Ideally, gridmix should set many job specific configuration properties like
> io.sort.mb, io.sort.factor, etc when running simulated jobs to get the same
> effect of original/real job in terms of spilled records, number of merges,
> etc.
> TraceBuilder should bring in all these properties into the generated trace
> file.
