> Currently the number of map and reduce slots have to be configured manually, which is reasonable for homogeneous clusters. However, as the clusters start to change over time it becomes rather painful to administer and configure. We should start thinking along the direction of auto-magically configuring the slots based on available resources on the node such as RAM, CPU, disk etc.
