Subject Re: Benchmarking pipelined MapReduce jobs
Date Thu, 24 Feb 2011 11:28:14 GMT
Thanks for your help! 

I had a look at the gridmix_config.xml file in the gridmix2 directory. However, I'm having
difficulties to map the descriptions of the simulated jobs from the README-file
1) Three stage map/reduce job
2) Large sort of variable key/value size
3) Reference select
4) API text sort (java, streaming)
5) Jobs with combiner (word count jobs)

to the jobs names in gridmix_config.xml: 

I would really appreciate any help, getting the right configuration! Which job do I have to
enable to simulate a pipelined execution as described in "1) Three stage map/reduce job"?

FWIU, it lets you define the # of jobs for different workloads and categories.

In its README-file it says that part of this benchmark is a "Three stage map/reduce job".

in order to only run this job (without the rest of the "Gridmix" benchmark)?
