Subject [jira] Commented: (MAPREDUCE-2112) Create a Common Data-Generator for Testing Hadoop
Date Tue, 05 Oct 2010 16:53:33 GMT

Olga Natkovich commented on MAPREDUCE-2112:
-------------------------------------------

It is important that the tool supports different column distribution so that we can simulate
different kinds of data with it.

> It is useful to have a common data-generator for testing Hadoop and related projects.
Such a tool
> should be able to generate data in a specified format and should be able to use a Hadoop
cluster
> for speeding up the data-generation. This tool can then be used across Hadoop (e.g. GridMix3),
> Pig, Hive, etc. reducing the need for each project to invent something like this itself.
> We can use the data-generator used in PigMix2 (PIG-200) as a starting point. It is described
> in [http://wiki.apache.org/pig/DataGeneratorHadoop]. Since it depends on the SDSU
> Java library ([http://www.eli.sdsu.edu/java-SDSU/]) released under the GNU GPL, it has
to be
> modified a bit to eliminate this dependency before it can be included in Apache Hadoop.
