Runping Qi commented on HADOOP-4627:
------------------------------------
The mail goal for gridmix is to allow a developer to create a reasonable mix
jobs so that they can use that to establish a baseline for their cluster
running a specific of Hadoop, and then test the potential impact of any changes
made to hadoop and/or the clutser.
It can also be used to uncover potential performance issues of a specific
Hadoop version and/or a specific cluster configuration.
It is believed to be generic enough such that a developer can easily tweak the
scripts to generate specific job mixes that are most appropriate for their
specific need, but it cannot be tuned to be the best mix that fits all needs.
Gridmix version two is along the same theme, but with a more efficient job
submission mechanism and provides more flexibility.

> The new gridmix differs from the original gridmix in the following ways:
> 1. Use an xml config file to specify the types and sizes mix of a mix load.
> This provides better granularity control.
> 2. Use JobControl to submit gridmix load, instead of shell script.
> 3. Include Pig jobs.
