I want to have multiple reducers in a Hadoop job to recreate the sorting problem described in the following Bog post:
Unfortunately the number-reducers property of the hadoop job does not work for me. Also I failed to set the property over the JobFactoryBean.
I have 2 VM's running as master/slave. Maybe there are some restrictions, which I don't understand, so there is just one reducer started.
For a longer description of the Problem + configuration snippets, see the post on stackoverflow.
