Hi, In order to simplify some data crunching for a client, I threw together some code that allows you to run MapReduce jobs over data in a MySQL table.
The code is heavily inspired by the MapReduce layer for HBase and works much like it. However, it's mainly meant to be used for development, as in it's current form, but could potentially be of use for people that must keep their data in a relational database and cannot migrate to HBase for some reason (without all the benefits of HBase of course). Needless to say, the code is a hack and has a lot of issues. Code is here [1]. If people find it useful, I can clean it up somewhat and put it in JIRA. - Fredrik [1] http://www.avafan.com/~fredrik/hadoop/
